• Question 1 of 5 1. Question With reference to the above passage, the following assumptions have been made: I. The diversification of rural employment beyond agriculture is a natural and necessary process of economic development. II. Institutional neglect of non-farm activities is the primary cause of rural unemployment in India. Which of the above assumptions is/are valid? (a) I only (b) II only (c) Both I and II (d) Neither I nor II Correct Answer: (a) Explanation: Assumption I is correct: The passage describes the growth of rural non-farm activities as an ongoing transformation that contributes significantly to household incomes.

It only mentions that the lack of institutional support and skills training limits the quality and security of jobs, not that it solely causes unemployment.

They all meet on Saturday. Now, Taking LCM = 11, 22, 13 = 286 Thus all meet on the 286th day. 1st meeting is on Saturday So, second meeting = 286/7 = 40 weeks and 6 odd days Thus second meeting is on Saturday + 6 odd days = Friday Hence option (b) is correct Incorrect Solution: B Given that, Riya visits the club on every 11th day. Karan visits on every 22nd day. Meera visits on every 13th day. They all meet on Saturday. Now, Taking LCM = 11, 22, 13 = 286 Thus all meet on the 286th day. 1st meeting is on Saturday So, second meeting = 286/7 = 40 weeks and 6 odd days Thus second meeting is on Saturday + 6 odd days = Friday Hence option (b) is correct

#### 4. Question

Riya visits the club every 11th day; Karan every 22nd day; Meera every 13th day. If all three met on a Saturday, then on which day will they meet again?

• (a) Thursday

• (b) Friday

• (c) Saturday

• (d) Sunday

Solution: B

Given that,

Riya visits the club on every 11th day. Karan visits on every 22nd day. Meera visits on every 13th day. They all meet on Saturday.

Taking LCM = 11, 22, 13 = 286

Thus all meet on the 286th day.

1st meeting is on Saturday

So, second meeting = 286/7 = 40 weeks and 6 odd days

Thus second meeting is on Saturday + 6 odd days = Friday

Hence option (b) is correct

Solution: B

Given that,

Riya visits the club on every 11th day. Karan visits on every 22nd day. Meera visits on every 13th day. They all meet on Saturday.

Taking LCM = 11, 22, 13 = 286

Thus all meet on the 286th day.
