36 persons working 8 hours a day can do 3 units of work in 12 days. How many persons are required to do 5 units of that work in 16 days, if they work for 6 hours a day?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 60
We know that:
[M1 × D1 × H1]/W1 = [M2 × D2 × H2]/W2
So,
[36 × 12 × 8]/3 = [M2 × 16 × 6]/5
⇒ 144 × 5 = M2 × 12
⇒ M2 = 12 × 5 = 60 persons
