30 men are engaged to a work by a contractor for 6 days. They work for 4 days but due to some reasons only 50% of the work is completed. How many more men should be engaged to work to complete the work in a given period of time. Correct Answer 30 men

Given time = 6 days 

Total men = 30 

Let the extra men be x

Using formula, M1D1/W1 = M2D2/W2

30 × 4 = (30 + x) × 2

∴ x = 30 men
