Question

27 men can do a piece of work in 48 days. 12 men can finish same work in….. days.​

Answer 1

Answer:

12 men can complete the work in 36 days.

∴ 12×36 men can complete the work in 1 day.

Again, 18 women can complete the work in 60 days.

∴ 18×60 women can complete the work in 1 day.

12×36 men = 18×60 women

=> 2 men = 5 women

Now, 8 men + 20 women

= (4×5+20) women = 40 women

∴ 18 women complete the work in 60 days.

∴ 40 women' 20 days' work

= 40×2018×60=2027

∴ Remaining work

= 1 - 2027 = 727

∵ 18×60 women do 1 work in 1 day.

∴ 1 woman does

= 118×60 work in 1 day

∴ 1 woman does in 4 days

= 418×60 = 118×15 work

∴ 118×15 work is done in 4 days by 1 Woman

∴ 727 work is done in 4 days

by = 18×15×727 = 70 women
