Tank A contains 6 times as much water as Tank B. How much water must Mohan transfer from Tank A to Tank B so that each tank contains 70 litres of water?
  • a)
    50 litres
  • b)
    60 litres
  • c)
    75 litres
  • d)
    120 litres
Correct answer is option 'A'. Can you explain this answer?

Aditi Sharma answered
Let quantity of water in tank B be x litres.
Then quantity of water in the tank A=6x litres
Total water in both the tanks =x+6x
=140 liters
⇒7x=140⇒x=20
∴ Water in tank B=20 litres
⇒ Water in tank A=20×6=120 litres
So, quantity of water to be transferred from tank A to tank B, so that each tank contains 70 litres= 70 −20=50 litres
Therefore, 50 liters  of water should be transferred.

A shopkeeper mixed 4.75 kg of hazelnuts with 0.75 kg of raisins. He packed the mixture equally into 5 boxes. What is the weight of each box?
  • a)
    1.25 kg 
  • b)
    1.1 kg
  • c)
    1.55 kg 
  • d)
    1.2 kg
Correct answer is option 'B'. Can you explain this answer?

Aditi Sharma answered
weight of hazelnut = 4.75kg
weight of raisins = 0.75 kg
total weight = 4.75 +0.75 = 5.5kg
No of box = 5
therefore weight of each box = total weight / no of box
= 5.5kg/ 5
= 1.1kg

What is the mass 20 such?

  • d)
    180 kg
Correct answer is option 'B'. Can you explain this answer?

  • On left side 12 balls
  • On right side 7 balls and 40 kg
  • So as both side weigth are equal so equating them
  • Let x be the weight of a single ball
  • 12x=7x+40
  • 5x=40
  • x=8
  • The mass of 20 such balls will be 160kg

Understanding the Problem
To find the weight of Aman's bag, we need to establish the relationship between Aman's bag and Ajay's bag based on the information provided.
Given Information
- Ajay's bag weight: 4.72 kg
- Aman's bag is 2.14 kg lighter than Ajay's bag.
Calculating Aman's Bag Weight
To find the weight of Aman's bag, we can use the formula:
Weight of Aman's bag = Weight of Ajay's bag - Difference in weight
Substituting the known values:
- Weight of Aman's bag = 4.72 kg - 2.14 kg
Performing the Calculation
1. Start with Ajay's bag weight: 4.72 kg
2. Subtract the difference: 2.14 kg
The calculation is:
- 4.72 kg - 2.14 kg = 2.58 kg
Conclusion
Thus, the weight of Aman's bag is 2.58 kg.
Final Answer
The correct option is (a) 2.58 kg.
This methodical breakdown helps in understanding how to approach similar problems involving differences in weights or other measurable attributes.

Understanding the Conversion
To convert measurements from meters and centimeters to centimeters alone, we need to follow a simple conversion rule:
- 1 meter (m) is equal to 100 centimeters (cm).
Breaking Down the Measurement
The given measurement is 26 meters and 6 centimeters. We will convert each part into centimeters.
Step 1: Convert Meters to Centimeters
- For the 26 meters:
- 26 m = 26 × 100 cm = 2600 cm
Step 2: Combine with Centimeters
- Now we add the 6 centimeters to the converted meters:
- Total in centimeters = 2600 cm + 6 cm = 2606 cm
Final Result
Thus, the total measurement of 26 m 6 cm is 2606 cm.
Options Review
Now, let's review the options provided:
- a) 2606 cm ✔️ (Correct answer)
- b) 20 cm
- c) 2066 cm
- d) 206 cm
The correct choice is clearly option A (2606 cm), as we calculated.
Summary
- Convert meters to centimeters by multiplying by 100.
- Add any remaining centimeters to the total.
- The final answer for the conversion of 26 m 6 cm is 2606 cm.
This step-by-step approach helps in understanding how to convert between different units of measurement effectively!

What is the capacity of the?
  • a)
    12 litres
  • b)
    24 litres
  • c)
    20 litres
  • d)
    18 litres
Correct answer is option 'B'. Can you explain this answer?

  • 1 bucket = 4 jugs
  • 2 jugs = 3 litres
  • If 2 jugs = 3 litres, then:
    Another 2 jugs will also be 3 litres.
  • So, 4 jugs = 3 litres + 3 litres = 6 litres.
    Therefore, 1 bucket = 6 litres.
  • The container has 4 buckets.
    Each bucket is 6 litres, so:
    4 buckets = 6 litres × 4 = 24 litres.


How much postage is needed to send a local mail of weight 310 g?

    Rs. 25
  • c)
    Rs. 30
  • d)
    Rs. 27.50
Correct answer is option 'B'. Can you explain this answer?

Avinash Patel answered
390g would be split in 60g and 250g 
and 250g = 5 x 50g
so for first 60g 12.5Rs and for every 50g x 2.5 
12.50 + 5 × 2.5 = Rs.25
