Q.

28 Men and 52 women working together completes a work in 22.5 days. 35 men and 65 women working together on same work will complete it in how many days?

View Answer

Correct choice: B

Explanation:

Clearly total persons are increased in 28/35 :: 52/65 = 4:5. As time is inversely proportional to men, so total time will decrease in the ratio 5:4. Hence, 22.5 x 4/5 = 18 days.
