Ten women can do a work in six days. Six men can complete the same work in five days. What is the ratio between the capacity of a man and a woman?
Choose the correct choice
A) 1:2 B) 2:1 C) 2:3 D) 3:2 E) None of these
Explanation:   (10 × 6) women can complete the work in 1 day.   ∴ 1 woman's 1 day's work = 1/60   (6 × 5) men can complete the work in 1 day.   ∴ 1 man's 1 day's work = 1/30   so, required ratio =1/30 : 1/60= 2:1   Answer: 2:1
