The given statements can be expressed diagrammatically as follows:
Total distance travelled towards the East = 20 + 420+4 = 2424 m.
Total distance travelled towards the North = -3 + 10−3+10 = 77 m.
Distance from the starting point can be found using the Pythagoras theorem.
Total distance travelled towards the East = 20 + 420+4 = 2424 m.
Total distance travelled towards the North = -3 + 10−3+10 = 77 m.

Shubham Sharma answered |
17 - 12 = 5
25 - 17 = 8
36 - 25 = 11
50 - 36 = 14
As we can see, the difference between 2 consecutive numbers in the series are in an AP.
The next term must be 50 + 17 = 67.
Therefore, 68 is the incorrect term in the series and hence, option D is the right answer.

Gorbachev's reforms were gradualist and maintained many of the macroeconomic aspects of the command economy (including price controls, inconvertibility of the rouble, exclusion of private property ownership, and the government monopoly over most means of production). His goal was quite plain: to bring the Soviet Union up to par economically with the West. He never aimed to have any strict control over government and people.

Given information:
- The average age of 4 boys is 22.5.
- When a new boy is included, the average age decreases by 6 months.
To find:
- The age of the new boy.
Let's solve this problem step by step:
Step 1: Find the sum of ages of the 4 boys.
- The average age of 4 boys is 22.5, so the sum of their ages is 4 * 22.5 = 90.
Step 2: Find the sum of ages of all 5 boys.
- Since the average age decreases by 6 months when the new boy is included, the sum of ages of all 5 boys is 90 - 6 = 84.
Step 3: Find the age of the new boy.
- The sum of ages of all 5 boys is 84.
- Subtracting the sum of ages of the original 4 boys (90) from the sum of ages of all 5 boys (84), we get the age of the new boy.
- New boy's age = 84 - 90 = -6.
Since it is not possible for someone's age to be negative, we made a mistake somewhere in our calculations.
Let's revisit the problem:
Step 1: Find the sum of ages of the 4 boys.
- The average age of 4 boys is 22.5, so the sum of their ages is 4 * 22.5 = 90.
Step 2: Find the sum of ages of all 5 boys.
- Since the average age decreases by 6 months when the new boy is included, the sum of ages of all 5 boys is 90 - 6 * 5 = 90 - 30 = 60.
Step 3: Find the age of the new boy.
- The sum of ages of all 5 boys is 60.
- Subtracting the sum of ages of the original 4 boys (90) from the sum of ages of all 5 boys (60), we get the age of the new boy.
- New boy's age = 60 - 90 = -30.
Again, we obtained a negative age which is not possible. It seems there is an error in the given information or the problem itself.

In British India, the Vernacular Press Act (Act of 1878) was enacted to curtail the freedom of the Indian pressand prevent the expression of criticism toward British policies—notably, the opposition that had grown with the outset of the Second Anglo-Afghan War (1878–80). The act was proposed by Lord Lytton, then Viceroy of India, and was unanimously passed by the Viceroy's Council on March 14, 1878.

Shubham Sharma answered |
To be divisible by 11, (sum of digits in odd places)-(sum of digits in even places) must be divisible by 11.
Lets check option A,
734867 => sum of digits in odd places = 7+4+6 = 17 & that of even places = 3+8+7 = 18, difference = 18-17 = 1 (not divisible by 11)
Lets check option B,
724867 => sum of digits in odd places = 7+4+6 = 17 & that of even places = 2+8+7 = 17, difference = 17-17 = 0 (divisible by 11)
So the answer is option B.

Mita Mehta answered |
Let the quantity of Type 1 = k and that of Type 2 = 2k
Let x be the cost price of the mixture,
k(12)+2k(18) = (2k+k)(x)
12k+36k = 3kx
48k = 3kx
16 = x
CP = 16/- and SP = 20/-
Profit = SP - CP = 20 - 16 = 4/-
Profit % = \frac{4}{16}\times 100 = 25164×100=25%

Let us replace the symbols with the actual operators.
13 - 13 / 3 - 63 * 9 + 2 -5 = 13 * 13 + 3*63/9 - 2*5
Applying BODMAS rule, we get, 169 + 3*7 - 10 = 180
Therefore, option B is the right answer.
Therefore, option B is the right answer.

Rajeev Khanna answered |
The boiling point of water in degrees centigrade is 100 degrees.
We now have to convert this to Farenheit.
We now have to convert this to Farenheit.
We know that C = 5/9*(F-32)
Or F = 9/5C + 32
Or F = 9/5C + 32
So, converting 100 degrees centigrade into Farenheit, we get 9/5*100 + 32 = 212 degrees.

Mira Chavan answered |
Explanation in English :
Bhim’s 1 day work = 1/15
∴ Bhim’s 10 day work = 10 * 1/15 = 2/3
Remaining work = (1 – 2/3) = 1/3
Now, 1/18 work is done by Amar in 1 day.
∴ 1/3 work is done by Amar in (18 * 1/3) = 6 days.

Read the following passage carefully and answer the questions that follow:
The end of the Second World War is a landmark in contemporary world politics. In 1945, the Allied Forces, led by the US, Soviet Union, Britain and France defeated the Axis Powers led by Germany, Italy and Japan, ending the Second World War (1939- 1945). The war had involved almost all the major powers of the world and spread out to regions outside Europe including Southeast Asia, China, Burma (now Myanmar) and parts of India’s northeast. The war devastated the world in terms of loss of human lives and civilian property. The First World War had earlier shaken the world between 1914 and 1918.The end of the Second World War was also the beginning of the Cold War. The world war ended when the United States dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki in August 1945, causing Japan to surrender. Critics of the US decision to drop the bombs have argued that the US knew that Japan was about to surrender and that it was unnecessary to drop the bombs. They suggest that the US action was intended to stop the Soviet Union from making military and political gains in Asia and elsewhere and to show Moscow that the United States was supreme. US supporters have argued that the dropping of the atomic bombs was necessary to end the war quickly and to stop further loss of American and Allied lives. Whatever the motives, the consequence of the end of the Second World War was the rise of two new powers on the global stage. With the defeat of Germany and Japan, the devastation of Europe and in many other parts of the world, the United States and the Soviet Union became the greatest powers in the world with the ability to influence events anywhere on earth.Q.

Kajal Banerjee answered |
Transit accommodation refers to the temporary housing provided to slum dwellers in a metro city. It serves as a transitional solution while permanent housing options are explored or developed for the residents. This type of accommodation plays a crucial role in addressing the housing needs of slum dwellers and improving their living conditions.
Transit accommodation offers several benefits and serves multiple purposes:
1. Temporary Solution:
Transit accommodation provides a temporary shelter for slum dwellers who may be displaced due to various reasons such as urban development projects, natural disasters, or eviction. It ensures that these individuals have a safe and secure place to stay during the transition period.
2. Housing Upgradation:
Many slum dwellers live in substandard and overcrowded conditions with limited access to basic amenities. Transit accommodation offers an opportunity to improve their living conditions by providing better housing facilities, sanitation, and access to services like water, electricity, and healthcare.
3. Rehabilitation and Resettlement:
Transit accommodation is often part of a larger rehabilitation and resettlement plan for slum dwellers. It helps in the process of relocating slum dwellers to more suitable and sustainable housing options, ensuring their well-being and integrating them into the urban fabric.
4. Social Integration:
Transit accommodation also promotes social integration by bringing slum dwellers closer to mainstream society. By providing them with improved living conditions and access to basic amenities, it helps reduce the gap between slum areas and the rest of the city.
5. Planning and Development:
Transit accommodation serves as a crucial tool in urban planning and development. It allows authorities to clear slum areas for redevelopment projects while ensuring that the affected residents are provided with temporary housing options. This approach helps in creating a more inclusive and sustainable urban environment.
Overall, transit accommodation plays a vital role in addressing the housing needs of slum dwellers in a metro city. It offers a temporary solution, promotes housing upgradation, facilitates rehabilitation and resettlement, fosters social integration, and aids in urban planning and development.

Prashanth Nair answered |
’Likes’ is the term common to both the sentences. Therefore, the code for ‘likes’ is ‘ta’. Exactly one among ‘ja’ and ‘ru’ and exactly one among ‘ki’ and ‘la’ must be used in the code for ‘Ram likes Carey’. Option C violates this condition. Therefore, option C cannot be the code and hence, it is the right answer.

Aashna Chauhan answered |
D has an equal number of persons weighing heavier than him and lighter than him. Therefore, D must be the third heaviest person. E is lighter than D but he is not the lightest. Therefore, E must be the second lightest person. The number of persons heavier than A is same as the number of persons lighter than E. Therefore, A must be the second heaviest person.
C is not the heaviest person. Therefore, C must be the lightest person and B must be the heaviest person among the five persons. No one weighs heavier than B. Therefore, 0 is the correct answer. Hence, option A is the correct answer.
