Question

16 men alone can complete a piece of work in 20 days, whereas 8 men and 5 women together take 32 days to complete the same piece of work. In how many days can 16 women alone complete the piece of work? Answer

Answer 1

Given
Case - 1

Men =16
Day=20

Work done=menxday

=16x20=320units

Now the same work done by 8men and 5 women

In 32day

(8m+5w)x32=320

8m+5w=320/32

8m+5w=10

5w=10-8=2m

So work done by 5 womens= work done by 2 men

1 women=2/5 unit in a day

16 women will do =2/5 x 16 =32/5

To do 320unit

Time=320/(32/5)

Time=320x5/32

Time=50day
