Question

A brick work in a factory can be completed in 24 days by 30 brick layers. How many men are needed to complete it in 20 days?​

Answer 1

than we have to divide 30÷24=1.25

1.25X20=25

Answer 2

Answer:

36

Step-by-step explanation:

As we know, this is the case of inverse proportion, so let the no of men be x . Now

⇒ 24 × 30 = 20 × x

⇒ 720/20 = x

∴ x = 36

So 36 men would be required to do work in 20 days, which means 6 more men are required to complete the brick work.
