12 men can do a piece of work in 24 days. How many days are needed to go complete the work, if 8 men do this work?
Correct Answer: 36
Explanation:
Given, M1 = 12, M2 = 8 , D1 = 24 , W1 = 1, W2 = 1
According to the formula,
M1D1W2 = M2D2W1
⇒ 12 x 24 x 1= 8 x D2 x 1
∴ D2 = (12 x 24)/8
= 12 x 3 = 36 days
