Question

If 8 boys and 12 women can fo a piece of work in 25 days, in how many days can the work be done by 6 boys and 11 woman working together.

Answer 1

If 12 men or 18 women can do a piece of work in 14 days, how long will 8 men and 16 women take to finish the work?

12 men work = 18 women work

so 1 men work = 18/12 women work

i.e. 1 men work = 1.5 women work. ...........(1)

So total amount of work to be done by women = 18*14 = 252

8 men and 16 women will take time

or from equation 1

12 women + 16 women will take time = 28 women will take time

time = work / no of women= 252/28

time=9 days
