4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it ?

View Answer

Correct choice: A

Explanation:

Let 1 man's 1 day work = x and 1 woman's 1 day work = y. Then, 4x + 6y = 1/8 and 3x + 7y = 1/10 Solving these two equations, we get: x = 11/400 and y = 1/400 10 woman's 1 day work = (1/400 x 10) = 1/40. Hence, 10 women will complete the work in 40 days.
