Question

If two painters can complete 3 rooms in 4 hours, how many painters would it take to do 120 rooms in 5 hours?

Answer 1

Answer:

64 painters

Step-by-step explanation:

We are given two painters can complete 3 rooms in 4 hours.

We are required to find  how many painters would it take to do 120 rooms in 5 hours.

Let it take x painters to do 120 rooms in 5 hours.

So, using man power method :

$\frac{2\times4}{3} =\frac{x\times5}{120}$

$\frac{8}{3} =\frac{5x}{120}$

$\frac{8}{3} =\frac{x}{24}$

$8=\frac{x}{8}$

$8\times 8=x$

$64=x$

Hence 64 painters are required to paint 120 rooms in 5 hours.
