Question

If 10 women can build a wall 40m long and 6m high in 24 days, then how many women are required to build another wall,which is 15m long and 12m high in 15 days?

Answer 1

10 women build 240m^2 area in 24 days
1 women build 24m^2 area in 24 days
1 women build 1m^2 area in 1 day
so 15m×12m=180m^2 area
let X women can built 180m^2area in15 days
then X×15=180
X=12
