Question

10 men can construct a wall of 180 m long in 3 days how many men are required to construct 300 m long wall in 5 days

Answer 1

If 180m for 3 days then 1 day 10 men construct 180/3=60m

So 1men construct 60m/10men=6m in 1 day

For5 days 1men will construct 5*6=30m

For 300m we need 10 men...!!!
