Statement: A large number of people in ward X of the city are diagnosed to be suffering from a fatal malaria type.
Courses of Action:

The city municipal authority should take immediate steps to carry out extensive fumigation in ward X.

The people in the area should be advised to take steps to avoid mosquito bites.
Correct Answer
A. 1 and 2 are correct
Explanation
The statement mentions that a large number of people in ward X are diagnosed with a fatal malaria type. Given this information, it is necessary for both the city municipal authority and the people in the area to take action. The city municipal authority should carry out extensive fumigation in ward X to control the mosquito population and prevent the spread of malaria. Additionally, the people in the area should be advised to take steps to avoid mosquito bites, such as using mosquito repellents, wearing protective clothing, and using bed nets. Therefore, both courses of action are necessary and correct.
2.
Statement: Severe drought is reported to have set in several parts of the country.
Courses of Action:

Government should immediately make arrangement for providing financial assistance to those affected.

Food, water and fodder should immediately be sent to all these areas to save the people and cattle.
Correct Answer
C. Only 2 is correct
Explanation
The statement mentions that severe drought has set in several parts of the country. In such a situation, the immediate requirement would be to provide basic necessities like food, water, and fodder to the affected areas to save the people and cattle. This aligns with the second course of action, which suggests sending immediate assistance to these areas. However, the first course of action, which suggests providing financial assistance, may not directly address the urgent need for basic necessities in the affected areas. Therefore, only the second course of action is correct.
3.

Courses of Action:

The government should make adequate arrangements to provide safe drinking water to all its citizens.

The people should be educated about the dangers of drinking polluted water.
Correct Answer
D. 1 and 2 are correct
Explanation
Both courses of action are correct in addressing the issue of people dying from drinking polluted water during the summer. The government should take responsibility and make adequate arrangements to provide safe drinking water to all its citizens to prevent further deaths. Additionally, educating the people about the dangers of drinking polluted water will help raise awareness and encourage them to make informed choices to protect their health. Both actions are necessary to effectively tackle the problem.

Statement: Most of those who study in premier engineering colleges in India migrate to developed nations for better prospects in their professional pursuits.
Courses of Action:

All the students joining these colleges should be asked to sign a bond at the time of admission to the effect that they will remain in India at least for ten years after they complete education.

All those students who desire to settle in the developed nations should be asked to pay entire cost of their education which the government subsidises.
Correct Answer
C. Only 2 is correct
Explanation
The statement suggests that most students from premier engineering colleges in India migrate to developed nations for better prospects. The correct answer states that only option 2 is correct. This implies that asking students who desire to settle in developed nations to pay the entire cost of their education, which the government subsidizes, is a suitable course of action. This action would ensure that students who plan to settle abroad bear the financial burden themselves, rather than relying on government subsidies.
5.
Statement: There is an unprecedented increase in migration of villagers to urban areas as repeated crop failure has put them into precarious financial situation.
Courses of Action:

The villagers should be provided with alternate source of income in their villages which will make them stay put.

The migrated villagers should be provided with jobs in the urban areas to help them survive
Correct Answer
A. Only 1 is correct
Explanation
The statement mentions that the migration of villagers to urban areas is due to repeated crop failure and precarious financial situation. Therefore, providing the villagers with an alternate source of income in their villages would address the root cause of the migration and encourage them to stay in their villages. On the other hand, providing jobs in urban areas to the migrated villagers would not solve the problem of crop failure and financial instability in the villages, and may even contribute to overcrowding and competition for limited resources in urban areas. Therefore, only the first course of action is correct.

Father is aged three times more than his son Ronit. After 8 years, he would be two and a half times of Ronit's age. After further 8 years, how many times would he be of Ronit's age?
Correct Answer
A. 2 times
Explanation
After 8 years, the father would be two and a half times Ronit's age. This means that if Ronit's age is represented by x, the father's age would be 2.5x. After further 8 years, Ronit's age would be x+16 and the father's age would be 2.5x+16. To find how many times the father's age is of Ronit's age, we divide the father's age by Ronit's age: (2.5x+16)/(x+16). Simplifying this expression, we get 2.5. Therefore, the father would be 2 times Ronit's age.

The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?
Correct Answer
A. 4 years
Explanation
The sum of ages of 5 children born at intervals of 3 years each is 50 years. This means that the ages of the children form an arithmetic sequence with a common difference of 3. Let's assume the age of the youngest child is x. The ages of the other 4 children would be x+3, x+6, x+9, and x+12. Adding up these ages gives us 5x+30=50. Solving this equation, we find that x=4. Therefore, the age of the youngest child is 4 years.

In the first 10 overs of a cricket game, the run rate was only 3.2. What should be the run rate in the remaining 40 overs to reach the target of 282 runs?
Correct Answer
A. 6.25
Explanation
To find the required run rate for the remaining 40 overs, we need to consider the total number of runs needed to reach the target and the number of overs remaining. The total runs needed to reach the target is 282  (3.2 * 10) = 282  32 = 250. Therefore, the required run rate for the remaining 40 overs is 250/40 = 6.25.

A family consists of grandparents, parents and three grandchildren. The average age of the grandparents is 67 years, that of the parents is 35 years and that of the grandchildren is 6 years. What is the average age of the family?
Correct Answer
B. 31 5/7
Explanation
The average age of the grandparents is 67 years, the average age of the parents is 35 years, and the average age of the grandchildren is 6 years. To find the average age of the family, we need to add up all the ages and divide by the total number of family members. Since there are 2 grandparents, 2 parents, and 3 grandchildren, the total number of family members is 7. Adding up the ages (67 + 67 + 35 + 35 + 6 + 6 + 6) gives us 222. Dividing 222 by 7 gives us 31 5/7, which is the average age of the family.

There are two examinations rooms A and B. If 10 students are sent from A to B, then the number of students in each room is the same. If 20 candidates are sent from B to A, then the number of students in A is double the number of students in B. The number of students in room A is:
Correct Answer
C. 100
Explanation
If we let the number of students in room A be x, and the number of students in room B be y, we can create two equations based on the given information. The first equation is x  10 = y + 10, which represents the fact that if 10 students are sent from A to B, then the number of students in each room is the same. The second equation is x = 2(y  20), which represents the fact that if 20 candidates are sent from B to A, then the number of students in A is double the number of students in B. By solving these equations simultaneously, we find that x = 100, which means there are 100 students in room A.
