Question

210 mens working 12 hours a day can finish a job in 18 days. How many men are required to finish the job in 20 days working 14 hours a day?​

Answer 1

The number of men required to do the job in 20 days working 14 hours per day = 162

Let the number of men required be x.

Units of work done = number of men × no. of days × no. of hours worked per day

=> Initial units of work done = final units of work done

=> 210 × 18 × 12 = x × 20 × 14

=> x = 162

The number of men required to do the job = 162
