Question

If 32 men working 12 hours a day can do a work in 15 days, how many men working 10 hours a day can do double that work in 24 days?

Answer 1

Let the required number of men be x.

Let P₁= 32, H₁ = 12, D₁ = 12, W₁ = 1

P₂ = x, H₂ = 10, D₂ = 24, W₂ = 1

x = 24 persons

To complete the same work 24 men needed.

To complete double the work 24 × 2 = 48 men are required.
