Question

12 men or 15 women can do the work in 24 days. In how many days the same work can be done by 8 men and 8 women

Answer 1

m stands for no. of men and w for number of women

Answer 2

According to question

12 men = 15 women

1men = 15/12 = 5/4 women

Now 8 men + 8 women will be reduced to

put 5/4 in place of men

= (8×5)/4 + 8

= 18 women

Now qns is

15 women do work in 24 days

So 1 women work = 24 × 15 = 360 days

and so 18 woman will do work in

= 360/18

Time taken by 8 men and 8 women is = 20days
