Question

10 men = 7 days 10 women = 14 days Calculate for how many days does 5 men and 10 women can do the work

Answer 1

Answer: 7 days

Method:

Assume Man as M

Woman as W

So, 10M= 7 days

1/M= 70 days -(a)

10W= 14 days

1/W= 140 days -(b)

Take the total work as 1

Take the number of days as F

(5/M + 10/W) F= 1 (insert values of (a) and (b))

F( 5/70 + 10/ 140) =1 (Calculation Done)

F( 1/7)= 1

1/7 = 1/F

Therefore

F= 7 days
