If 40 men build 4 buildings in 12 months how many men would be required to build 6 houses in 4 months?
- 114 men
- 140 men
- 180 men
- 160 men
Explanation
If 40 men can build 4 buildings in 12 months we can divide 4/12 which is 1/3..
40*3 is 120 men for 4 buildings and 120 is divided into 4 we get 30 men for 1 building..
so for buildings 30*2 = 60
120+60 is = 180
