I. (10 x 6) men can complete the work in 1 day. 1 man's 1 day's work = 1 60 II. 10 x 24 men + 10 x 24 women can complete the work in 1 day. 7 7 240 men's 1 day work + 240 women's 1 day work = 1. 7 7 240 x 1 + 240 women's 1 day's work = 1. 7 60 7 240 women's 1 day's work = 1 - 4 = 3 7 7 7 10 women's 1 day's work = 3 x 7 x 10 = 1 7 240 8 So, 10 women can finish the work in 8 days. III. (10 men's work for 3 days) + (10 women's work for 4 days) = 1 (10 x 3) men's 1 day's work + (10 x 4) women's 1 day's work = 1 30 men's 1 day's work + 40 women's 1 day's work = 1 Thus, I and III will give us the answer. And, II and III will give us the answer. Correct answer is (A).

II. 10 x 24 men + 10 x 24 women can complete the work in 1 day. 7 7 240 men's 1 day work + 240 women's 1 day work = 1. 7 7 240 x 1 + 240 women's 1 day's work = 1. 7 60 7 240 women's 1 day's work = 1 - 4 = 3 7 7 7 10 women's 1 day's work = 3 x 7 x 10 = 1 7 240 8 So, 10 women can finish the work in 8 days.

III. (10 men's work for 3 days) + (10 women's work for 4 days) = 1 (10 x 3) men's 1 day's work + (10 x 4) women's 1 day's work = 1 30 men's 1 day's work + 40 women's 1 day's work = 1

Thus, I and III will give us the answer. And, II and III will give us the answer. Correct answer is (A).
