Given Information:
- Ten boxes - C, D, E, F, G, H, I, J, K and L are kept one above the other in a single stack, but not necessarily in the same order.
- Only four boxes are kept between box L and box H, which is kept below box L.
- At least one box is kept above box D, which is kept immediately above box L.
- The number of boxes kept above box D is the same as the number of boxes kept below box K.
- Only two boxes are kept between box K and box I.
- Box C is kept immediately above box F, which is not kept adjacent to box D.
- Box G is kept above box E but below box J.
- More than two boxes are kept between box E and box G.
Solution:
To determine the position of box C, we need to analyze the given information step by step.
Step 1: Constraints related to box L and H
- Only four boxes are kept between box L and box H, and H is kept below L.
- From this, we can infer that L must be placed fifth from the top, and H must be placed ninth from the top.
Step 2: Constraints related to box D
- At least one box is kept above box D, and D is kept immediately above L.
- Since L is placed fifth from the top, D must be placed sixth from the top.
Step 3: Constraints related to box K
- The number of boxes kept above D is the same as the number of boxes kept below K.
- Since D is placed sixth from the top, the number of boxes above D is six. Therefore, the number of boxes below K is also six.
- Only two boxes are kept between box K and box I. From this, we can infer that K must be placed third from the top and I must be placed seventh from the top.
Step 4: Constraints related to box F
- Box C is kept immediately above box F, and F is not kept adjacent to D.
- Since C is placed above F, C must be placed higher than F in the stack. Therefore, C cannot be placed seventh from the top.
- Since F is not kept adjacent to D, F cannot be placed fifth from the top.
- Combining the above two observations, C must be placed sixth from the top.
Step 5: Constraints related to box G and E
- Box G is kept above box E but below box J.
- More than two boxes are kept between box E and box G.
- Since G is placed below J, J must be placed higher than G in the stack.
- From the above two observations, G cannot be placed seventh from the top.
- Since more than two boxes are kept between E and G, E cannot be placed fifth from the top.
- Combining the above two observations, G must be placed sixth from the top.
Final Answer:
Based on the above deductions, the position of box C is the fifth from the bottom. Therefore, the correct answer is option (c) Fifth from the bottom.
- Ten boxes - C, D, E, F, G, H, I, J, K and L are kept one above the other in a single stack, but not necessarily in the same order.
- Only four boxes are kept between box L and box H, which is kept below box L.
- At least one box is kept above box D, which is kept immediately above box L.
- The number of boxes kept above box D is the same as the number of boxes kept below box K.
- Only two boxes are kept between box K and box I.
- Box C is kept immediately above box F, which is not kept adjacent to box D.
- Box G is kept above box E but below box J.
- More than two boxes are kept between box E and box G.
Solution:
To determine the position of box C, we need to analyze the given information step by step.
Step 1: Constraints related to box L and H
- Only four boxes are kept between box L and box H, and H is kept below L.
- From this, we can infer that L must be placed fifth from the top, and H must be placed ninth from the top.
Step 2: Constraints related to box D
- At least one box is kept above box D, and D is kept immediately above L.
- Since L is placed fifth from the top, D must be placed sixth from the top.
Step 3: Constraints related to box K
- The number of boxes kept above D is the same as the number of boxes kept below K.
- Since D is placed sixth from the top, the number of boxes above D is six. Therefore, the number of boxes below K is also six.
- Only two boxes are kept between box K and box I. From this, we can infer that K must be placed third from the top and I must be placed seventh from the top.
Step 4: Constraints related to box F
- Box C is kept immediately above box F, and F is not kept adjacent to D.
- Since C is placed above F, C must be placed higher than F in the stack. Therefore, C cannot be placed seventh from the top.
- Since F is not kept adjacent to D, F cannot be placed fifth from the top.
- Combining the above two observations, C must be placed sixth from the top.
Step 5: Constraints related to box G and E
- Box G is kept above box E but below box J.
- More than two boxes are kept between box E and box G.
- Since G is placed below J, J must be placed higher than G in the stack.
- From the above two observations, G cannot be placed seventh from the top.
- Since more than two boxes are kept between E and G, E cannot be placed fifth from the top.
- Combining the above two observations, G must be placed sixth from the top.
Final Answer:
Based on the above deductions, the position of box C is the fifth from the bottom. Therefore, the correct answer is option (c) Fifth from the bottom.

Explanation:
Given Information:
- Mr. A walks from Point H towards north and reaches Point M after 8m.
- He then turns right and walks 6m to reach Point S.
- From Point S, he turns right again and walks 16m to reach Point V.
- Finally, he turns left and walks 4m to reach Point G.
- Mr. B walks from Point T towards west and reaches Point Q after 7m.
- He then turns left and walks 9m to reach Point P.
- Point P is north of Point G and east of Point S.
Determining the Direction:
- Point H is the starting point for Mr. A and Point T is the starting point for Mr. B.
- Mr. A walks towards north from Point H and Mr. B walks towards west from Point T.
- Therefore, the direction of Point H with respect to Point T would be the direction Mr. A is facing, which is towards the north-west.
Therefore, the correct answer is option D) South-west.

The ratio of the profit share of Mya, Lia, Zoe and Eva = (2P) * 12 : (3P) * 12 : (P + 500) * 4 : (5P/2) * 4
= 6P : 9P : (P + 500) : 5P/2
The profit share of Eva = 7800 * (5P/2)/6P
= 7800 * 5/12
= Rs.3250

Kabir Verma answered |
Let the numbers be 37a and 37b.
Then, 37a × 37b = 4107
⇒ ab = 3
Now, co-primes with product 3 are (1, 3).
So, the required numbers are (37×1, 37×3) i.e., (37, 111).
∴ Greater number = 111.
Hence, the correct option is (B).

Following above instructions will lead to below diagram
A & F → A is 4 km to west of F
C # F → C is 4 km to south of F
C % E → C is 1 km east of E
Using Pythagoras’ theorem,
AE2 = 42 + 32
AE2 = 25
AE = 5
So, the minimum distance between E and A is 5 km.
Hence, the correct option is (C).

The least possible Venn diagram for the given statements is as follows
Conclusions:
I. No bed is blanket → False (It is possible but not definite.)
II. Some table can be glass → False (as only bed is table is given that implies that all table are bed and table do not have any relationship with any other element except bed.)
III. Few bed are blanket → False (It is possible but not definite.)
Conclusion I and III forms complementary pair.
Thus, Either conclusion I or III follows.
Hence, the correct option is (C).

Tushar Das answered |
To solve this problem, we need to use the concept of weighted averages.
Given:
- 150 kgs of an alloy of gold and silver in the ratio 1:4
- x kgs of an alloy of gold and silver in the ratio 7:3
Let's calculate the amount of gold and silver in each alloy:
For the first alloy:
- Gold: 1/5 * 150 = 30 kgs
- Silver: 4/5 * 150 = 120 kgs
For the second alloy:
- Gold: 7/10 * x = 7x/10 kgs
- Silver: 3/10 * x = 3x/10 kgs
Now, let's calculate the total amount of gold and silver in the overall alloy:
Total gold = 30 + 7x/10
Total silver = 120 + 3x/10
To find the range of values x can take, we need to consider the percentage of gold in the overall alloy. It should be between 40% and 50%.
Let's calculate the percentage of gold in the overall alloy:
Gold percentage = (Total gold / Total weight) * 100
= (30 + 7x/10) / (150 + x) * 100
Now, let's calculate the minimum and maximum values of x that would result in a gold percentage between 40% and 50%:
Minimum value of x:
40% <= (30="" +="" 7x/10)="" (150="" +="" x)="" *="">
0.4 * (150 + x) <= 30="" +="">
60 + 0.4x <= 30="" +="">
400 + 4x <= 300="" +="">
100 <=>
x >= 100/3
Maximum value of x:
50% >= (30 + 7x/10) / (150 + x) * 100
0.5 * (150 + x) >= 30 + 7x/10
75 + 0.5x >= 30 + 7x/10
750 + 5x >= 300 + 7x
450 >= 2x
x <=>
Therefore, the range of values x can take is 100/3 ≤ x ≤ 225.
The correct answer is option 'C': 100 ≤ x ≤ 225.

Kabir Verma answered |
- Let’s start by tabulating the information given in (ii).
- Since Krishna finished the race before Megha and Sarika, Krishna must be one among the top 3.
- From (iv) we also know that Tarun was one among the top 3.
- So, either Megha or Sarika must be from Electrical and must be ranked 4. But since Sarika is from either Civil or CSE, Megha must be from Electrical.
- This means Sarika must definitely be 5th as she finishes after Megha.
- Since the person from Computer finished the race before the person from Electronics and Mechanical, he can’t be 5th.
- Thus, Sarika must be from Civil.
- This leaves Krishna with Computer. From (vi) we can conclude that Krishna must be 1st, Tarun 2nd, and Dilip 3rd.
From the table, we can see that only (D) holds true.
Hence, the correct option is (D).

Kabir Verma answered |
Since the mixtures are taken in the ratio 2 ∶ 4 ∶ 3
Suppose 40 litres, 80 litres and 60 litres of these mixtures are taken respectively∶
⇒ Alcohol in the vessel = 40 × 5/8 + 80 × 2/5 + 60 × 7/10 = 25 + 32 + 42 = 99 L
⇒ Water in the vessel = 40 × 3/8 + 80 × 3/5 + 60 × 3/10 = 15 + 48 + 18 = 81 L
∴ Ratio of Alcohol and water in the vessel = 99 ∶ 81 = 11 ∶ 9
Hence, the correct option is (D).

Pipe P alone fill the tank = 1/24 – 1/60 = 5/120 – 2/120 = 3/120 = 1/40 = 40 minuets
Pipe P double its efficiency:
The time taken by pipe P alone to fill the tank = 40 * 1/2 = 20 minutes
Pipe R reduced half of its efficiency:

The number of bicycles unsold = 80 x 5/2 = 200
Store B:
The number of bicycles sold = 90 x 2 = 180
The number of bicycles unsold = 120 x 5/2 = 300
Store C:
The number of bicycles sold = 160 x 2 = 320
The number of bicycles unsold = 50 x 5/2 = 125
Store D:
The number of bicycles sold = 110 x 2 = 220
The number of bicycles unsold = 100 x 5/2 = 250
Store E:
The number of bicycles sold = 180 x 2 = 360
The number of bicycles unsold = 60 x 5/2 = 150
The total number of bicycles manufactured in store B = 180 + 300 = 480

To solve this question, we need to follow the given equation step by step:
Step 1: Calculate the percentage of 1200.
% of 1200 = (8000/100) * 1200 = 96000
Step 2: Subtract 82 from the above result.
96000 - 82 = 95918
Step 3: Subtract 400 from the above result.
95918 - 400 = 95518
Step 4: Find the cube root of 8000.

To determine how H is related to T, we first need to analyze the family tree based on the given information:
1. Generational Outline:
- Y is the grandmother of M, indicating that Y is from the oldest generation.
- E, the father of M, is Y's son-in-law, meaning E is married to M's mother, who is Y's daughter.
- The only child of E (M) is in the second generation.
2. Relationship Clue:
- N is the brother-in-law of P and the son of Y, making P Y's child.
- T, stated as the only sister of P, is also Y's daughter, placing her in the same generation as E and N.
3. Understanding H's Relation:
- H is married to P, which means H is the son-in-law of Y.
- As T is P's sister, H becomes T's brother-in-law.
4. R's Role:
- R is the daughter of K and does not have any male children, but her specific relation to others is not central to determining H's relation to T.
Conclusion
- Therefore, with H married to P and T being P's sister, the relationship of H to T is that of a brother-in-law.

Given:
P = Rs. 12000
Time = 9 months = 3 quarter
Rate% p.a. = 16/4 = 4% per quarter
From formula:
= 1.2 × 1.04 × 04 × 104
= 13498.368
CI = A – P
= 13498.368 – 12000
= Rs. 1498.368
Hence, the correct option is (D).

Problem:
The value of simple interest and compound interest on a certain principal at a certain rate after two years is Rs. 2400 and Rs. 2544 respectively. Find the value of the principal.
Solution:
Let's assume the principal amount as P and the rate of interest as R.
Simple Interest:
The formula for simple interest is given by:
Simple Interest = (Principal * Rate * Time) / 100
Given that after two years, the simple interest is Rs. 2400. Therefore, we can write the equation as:
2400 = (P * R * 2) / 100
Compound Interest:
The formula for compound interest is given by:
Compound Interest = Principal * (1 + Rate/100)^Time - Principal
Given that after two years, the compound interest is Rs. 2544. Therefore, we can write the equation as:
2544 = P * (1 + R/100)^2 - P
Calculating the Principal:
We have two equations with two unknowns. To solve for the principal, we can eliminate one unknown by substituting the value of one variable from one equation into the other equation.
From the first equation, we can express R in terms of P as:
R = (2400 * 100) / (P * 2)
Substituting this value of R in the second equation:
2544 = P * (1 + ((2400 * 100) / (P * 2))/100)^2 - P
Simplifying this equation further, we get:
2544 = P * (1 + 1200/P)^2 - P
2544 = P * (1 + 2400/P + (1200/P)^2) - P
2544 = P + 2400 + 1440000/P - P
2544 = 2400 + 1440000/P
144 = 1440000/P
P = 1440000/144
P = 10000
Therefore, the value of the principal is Rs. 10000.
Answer:
The value of the principal is Rs. 10000. (Option D)
The value of simple interest and compound interest on a certain principal at a certain rate after two years is Rs. 2400 and Rs. 2544 respectively. Find the value of the principal.

Let's assume the principal amount as P and the rate of interest as R.
Simple Interest:
The formula for simple interest is given by:
Simple Interest = (Principal * Rate * Time) / 100
Given that after two years, the simple interest is Rs. 2400. Therefore, we can write the equation as:
2400 = (P * R * 2) / 100
Compound Interest:
The formula for compound interest is given by:
Compound Interest = Principal * (1 + Rate/100)^Time - Principal
Given that after two years, the compound interest is Rs. 2544. Therefore, we can write the equation as:
2544 = P * (1 + R/100)^2 - P
Calculating the Principal:
We have two equations with two unknowns. To solve for the principal, we can eliminate one unknown by substituting the value of one variable from one equation into the other equation.
From the first equation, we can express R in terms of P as:
R = (2400 * 100) / (P * 2)
Substituting this value of R in the second equation:
2544 = P * (1 + ((2400 * 100) / (P * 2))/100)^2 - P
Simplifying this equation further, we get:
2544 = P * (1 + 1200/P)^2 - P
2544 = P * (1 + 2400/P + (1200/P)^2) - P
2544 = P + 2400 + 1440000/P - P
2544 = 2400 + 1440000/P
144 = 1440000/P
P = 1440000/144
P = 10000
Therefore, the value of the principal is Rs. 10000.
Answer:
The value of the principal is Rs. 10000. (Option D)

Given Information:
- Nine persons Sonu, Raju, Monu, Tony, Titu, Sanju, Mohan, Sohan, and Rohan are seated in a row facing North.
- Mohan is sitting exactly in the middle of the row.
- Two people sit between Mohan and Raju.
- Rohan sits to the immediate right of Raju.
- Sohan sits at one of the extreme ends of the row.
- One person sits between Sohan and Tony.
- Titu is not an immediate neighbor of Mohan and Raju.
- Monu is an immediate neighbor of Tony.
- Sonu is not an immediate neighbor of Mohan and is not sitting at the end of the row.
Solution:
To find the condition regarding Titu, let's analyze the given information step by step.
Step 1: Mohan is sitting exactly in the middle of the row.
- The total number of persons in the row is 9.
- Since Mohan is sitting exactly in the middle, there are 4 persons to his left and 4 persons to his right.
- The seating arrangement looks like this: _ _ _ M _ _ _.
Step 2: Two people sit between Mohan and Raju.
- There are 4 persons to the left of Mohan. Two people sit between Mohan and Raju. So, Raju must be sitting at the leftmost end of the row. The seating arrangement looks like this: R _ _ M _ _ _.
Step 3: Rohan sits to the immediate right of Raju.
- Rohan sits to the immediate right of Raju, which means Rohan is sitting second from the leftmost end of the row. The seating arrangement looks like this: R Ro _ M _ _ _.
Step 4: Sohan sits at one of the extreme ends of the row.
- Sohan sits at one of the extreme ends of the row. Since Raju is at the leftmost end, Sohan must be at the rightmost end. The seating arrangement looks like this: R Ro _ M _ _ So.
Step 5: One person sits between Sohan and Tony.
- One person sits between Sohan and Tony. Since Sohan is at the rightmost end, Tony must be at the second position from the rightmost end. The seating arrangement looks like this: R Ro _ M _ T So.
Step 6: Titu is not an immediate neighbor of Mohan and Raju.
- Titu cannot be an immediate neighbor of Mohan or Raju. Since Raju is at the leftmost end and Rohan is to his immediate right, Titu cannot sit at the 3rd position from the leftmost end. Also, since Sohan is at the rightmost end and Tony is at the second position from the rightmost end, Titu cannot sit at the 4th position from the rightmost end. Therefore, the only possible position for Titu is the 4th position from the leftmost end. The seating arrangement looks like this: R Ro _ T M _ So.
Step 7: Conclusion
- From the seating arrangement, we can conclude that Titu is the immediate neighbor of Sohan and Tony. Therefore
- Nine persons Sonu, Raju, Monu, Tony, Titu, Sanju, Mohan, Sohan, and Rohan are seated in a row facing North.
- Mohan is sitting exactly in the middle of the row.
- Two people sit between Mohan and Raju.
- Rohan sits to the immediate right of Raju.
- Sohan sits at one of the extreme ends of the row.
- One person sits between Sohan and Tony.
- Titu is not an immediate neighbor of Mohan and Raju.
- Monu is an immediate neighbor of Tony.
- Sonu is not an immediate neighbor of Mohan and is not sitting at the end of the row.
Solution:
To find the condition regarding Titu, let's analyze the given information step by step.
Step 1: Mohan is sitting exactly in the middle of the row.
- The total number of persons in the row is 9.
- Since Mohan is sitting exactly in the middle, there are 4 persons to his left and 4 persons to his right.

Step 3: Rohan sits to the immediate right of Raju.
- Rohan sits to the immediate right of Raju, which means Rohan is sitting second from the leftmost end of the row. The seating arrangement looks like this: R Ro _ M _ _ _.
Step 4: Sohan sits at one of the extreme ends of the row.
- Sohan sits at one of the extreme ends of the row. Since Raju is at the leftmost end, Sohan must be at the rightmost end. The seating arrangement looks like this: R Ro _ M _ _ So.
Step 5: One person sits between Sohan and Tony.
- One person sits between Sohan and Tony. Since Sohan is at the rightmost end, Tony must be at the second position from the rightmost end. The seating arrangement looks like this: R Ro _ M _ T So.
Step 6: Titu is not an immediate neighbor of Mohan and Raju.
- Titu cannot be an immediate neighbor of Mohan or Raju. Since Raju is at the leftmost end and Rohan is to his immediate right, Titu cannot sit at the 3rd position from the leftmost end. Also, since Sohan is at the rightmost end and Tony is at the second position from the rightmost end, Titu cannot sit at the 4th position from the rightmost end. Therefore, the only possible position for Titu is the 4th position from the leftmost end. The seating arrangement looks like this: R Ro _ T M _ So.
Step 7: Conclusion
- From the seating arrangement, we can conclude that Titu is the immediate neighbor of Sohan and Tony. Therefore

Given information:
- A invests Rs. 10,000
- B invests Rs. 4000
- B receives Rs. 1200 as management fees
- A and B both receive 5% interest on their capital from the profit amount
- The remaining profit is distributed between A and B in the ratio of their investment
To find:
- Total share of A in the total annual profit of Rs. 4000
Calculations:
1. Calculation of interest:
- A's interest = 5% of Rs. 10,000 = Rs. 500
- B's interest = 5% of Rs. 4000 = Rs. 200
2. Calculation of remaining profit:
- Total profit = Rs. 4000
- Management fees = Rs. 1200
- Interest for A = Rs. 500
- Interest for B = Rs. 200
- Remaining profit = Total profit - Management fees - Interest for A - Interest for B
= Rs. 4000 - Rs. 1200 - Rs. 500 - Rs. 200
= Rs. 2100
3. Distribution of remaining profit:
- Ratio of A's investment to B's investment = 10000:4000 = 5:2
- Share of A = (Remaining profit * A's investment ratio) / (Sum of investment ratios)
= (2100 * 5) / (5 + 2)
= Rs. 1500
Therefore, the total share of A in the total annual profit of Rs. 4000 is Rs. 1500. Answer option (c) is correct.
- A invests Rs. 10,000
- B invests Rs. 4000
- B receives Rs. 1200 as management fees
- A and B both receive 5% interest on their capital from the profit amount
- The remaining profit is distributed between A and B in the ratio of their investment
To find:
- Total share of A in the total annual profit of Rs. 4000
Calculations:
1. Calculation of interest:
- A's interest = 5% of Rs. 10,000 = Rs. 500
- B's interest = 5% of Rs. 4000 = Rs. 200
2. Calculation of remaining profit:
- Total profit = Rs. 4000
- Management fees = Rs. 1200
- Interest for A = Rs. 500
- Interest for B = Rs. 200
- Remaining profit = Total profit - Management fees - Interest for A - Interest for B
= Rs. 4000 - Rs. 1200 - Rs. 500 - Rs. 200
= Rs. 2100
3. Distribution of remaining profit:
- Ratio of A's investment to B's investment = 10000:4000 = 5:2
- Share of A = (Remaining profit * A's investment ratio) / (Sum of investment ratios)
= (2100 * 5) / (5 + 2)
= Rs. 1500
Therefore, the total share of A in the total annual profit of Rs. 4000 is Rs. 1500. Answer option (c) is correct.

Problem Analysis:
Let's assume the initial amount of honey in the jar is x grams. After the first round, 20% of x grams is drawn out and replaced with a sugar solution. This process is repeated 4 times. We need to find the value of x.
Solution:
Let's solve this problem step by step:
Step 1: Calculate the amount of honey left after the first round.
After the first round, 20% of x grams of honey is drawn out, which is 0.2x grams. So, the amount of honey left after the first round is (x - 0.2x) grams = 0.8x grams.
Step 2: Calculate the amount of honey left after the second round.
After the second round, 20% of the honey left after the first round (0.8x grams) is drawn out. So, the amount of honey left after the second round is 0.8x - 0.2(0.8x) = 0.8x - 0.16x = 0.64x grams.
Step 3: Calculate the amount of honey left after the third round.
After the third round, 20% of the honey left after the second round (0.64x grams) is drawn out. So, the amount of honey left after the third round is 0.64x - 0.2(0.64x) = 0.64x - 0.128x = 0.512x grams.
Step 4: Calculate the amount of honey left after the fourth round.
After the fourth round, 20% of the honey left after the third round (0.512x grams) is drawn out. So, the amount of honey left after the fourth round is 0.512x - 0.2(0.512x) = 0.512x - 0.1024x = 0.4096x grams.
Step 5: Given that there is only 512 grams of honey left in the jar after the fourth round.
From step 4, we know that the amount of honey left after the fourth round is 0.4096x grams. We can set up the equation:
0.4096x = 512
Step 6: Solve the equation to find the value of x.
Dividing both sides of the equation by 0.4096:
x = 512 / 0.4096 = 1250 grams = 1.25 kg
Conclusion:
Therefore, the initial amount of honey in the jar was 1.25 kg, which corresponds to option A.

Rutuja Das answered |
Calculation of Marked Price:
- Let the marked price be x.
- After the first discount of 75%, the selling price becomes 25% of x, which is 0.25x.
- After the second discount of 70%, the selling price becomes 30% of 0.25x, which is 0.3 * 0.25x = 0.075x.
- Given that the selling price is Rs 7,500, we can write the equation as 0.075x = 7500.
- Solving for x, we get x = 7500 / 0.075 = Rs. 100,000.
Therefore, the marked price of the dress is Rs. 100,000.
- Let the marked price be x.
- After the first discount of 75%, the selling price becomes 25% of x, which is 0.25x.
- After the second discount of 70%, the selling price becomes 30% of 0.25x, which is 0.3 * 0.25x = 0.075x.
- Given that the selling price is Rs 7,500, we can write the equation as 0.075x = 7500.
- Solving for x, we get x = 7500 / 0.075 = Rs. 100,000.
Therefore, the marked price of the dress is Rs. 100,000.

Given Data
- Speed of Manoj in still water: 108 km/hr
- Speed of the river current: 5 m/s
Conversion of Units
- Convert the speed of the river from m/s to km/hr:
- 5 m/s = 5 * 18/5 = 18 km/hr
Effective Speeds
- Downstream Speed:
- Speed in still water + Speed of the current = 108 km/hr + 18 km/hr = 126 km/hr
- Upstream Speed:
- Speed in still water - Speed of the current = 108 km/hr - 18 km/hr = 90 km/hr
Average Speed Calculation
- Formula for Average Speed when covering the same distance upstream and downstream:
Average Speed = (2 * Downstream Speed * Upstream Speed) / (Downstream Speed + Upstream Speed)
- Substitute the values:
- Average Speed = (2 * 126 * 90) / (126 + 90)
- Calculate:
- Average Speed = (22680) / (216) = 105 km/hr
Conclusion
Thus, the average speed throughout the journey is 105 km/hr, confirming the correct answer is option 'D'.

Identifying the wrong number:
There seems to be a pattern in the given number series, where each number is obtained by multiplying the previous number by a certain value and then adding a specific number. To find the wrong number, we need to analyze this pattern and identify the discrepancy.
Analysis of the number series:
- 2 x 1 + 1 = 3
- 3 x 2 + 2 = 8
- 8 x 3 + 3 = 27
- 27 x 4 + 4 = 112
- 112 x 5 + 5 = 565 (not 560)
- 560 x 6 + 6 = 3366
Identifying the wrong number:
The wrong number in the series is 560, as it does not follow the pattern established by the other numbers in the series. The correct number should be 565.
Therefore, the wrong number in the given series is 560.

The total number of fans manufactured in 2015 = 1200
The total number of fans manufactured in all five years together = 1200 x 100/20 = 6000
The total number of fans manufactured in 2011 = 6000 x 21/100 = 1260
The total number of fans manufactured in 2012 = 6000 x 15/100 = 900
The total number of fans manufactured in 2013 = 6000 x 30/100 = 1800
The total number of fans manufactured in 2014 = 6000 x 14/100 = 840
The total number of fans manufactured in 2016 = 1260 x 6/7 = 1080
The ratio of the number of tower fans to window fans manufactured in 2016 = 125:100 = 5:4
The number of tower fans manufactured in 2016 = 1080 x 5/(5 + 4) = 1080 x 5/9 = 600
