Question

12 men or 15 women can do a piece of work in 21 days. Find the number of days required to complete the same work by 6 men and 10 women​

Answer 1

Answer:

12 men = 21 days

1 man = 252 days

1 man in 1 day = 1/252 of the work

6 men = 6/252 = 1/42 of the work

15 women = 21 days

1 woman = 315 days

1 woman in 1 day =1/315 of the work

10 women in 1 day = 10/315 = 2/63 of the work

so 6men + 10 women in 1 day = 1/42 +2/63 = 7/126= 1/18

ANSWER 18 days
