Question

A work force of 50 men with a contractor can finish a work in 5 months. In how many months the same work can be finish by 125 men

Answer 1

Answer:

Let the number of months required by men to finish a piece of work be ‘x’

• months Men 50 125 Time (months) 5 x
• We know k = xy
• 50 × 5 = 125 × x
• x = (50×5)/125 = 2
• ∴ 125 men require 2 months to do a piece of work.
