Question

18 women can complete a work in 12 days and 12 men can complete the same work in 9 days. In how many days will 8 men and 8 women complete that work

Answer 1

8 women, 1 day work= 8/(12*18)=1/27

8 men, 1 day work= 8/(9*12)=2/27

In 1 day 8 men & 8 women will complete (1/27)+(2/27)=3/27= 1/9

So the whole work will be completed in 9 days
