Question

15 men can build a 16.25 meter long wall up to a certain height in one day, how many men should be employed to build a wall of the same height but off length 26 meter in one day

Answer 1

26-16.5=9.75

Therefore, 9.75m long wall is built by 15 men

Let 26m long wall be built by 'x' men

Height of wall men

9.75 15

26 x

Cross multiplying we get

x=15×26÷9.75

x=40 men

Therefore 40 men are required to build a 26 m long wall in one day
