40 men can build a wall 20m*8m*1m in 60 days.how many men will required to build a another wall 25m*8m*1m in 40 days..
Option
a. 30
b. 40
c. 50
d. 75

• d. 75
  
  40Men---60 Days------(20*8*1)=160 m^3
  40Men---60*(2/3)=40Days---160*(2/3)=320/3 m^3
  For 320/3 m^3,40 men are required,
  So for (25*8*1)=200 m^3 men required= 200*40/(320/3)= 75
