Question

A contractor employs 360 men who can finish a certain piece of work in 11 months. How many more men must be employed to complete the work in 9 months?

Answer 1

Answer: 80 men should be employed more to complete the work in 9 months

Step-by-step explanation:

Men                                    360                       x

Time(in months)                11                          9

As it is inversely related

therefore we have

$360\times 11= x\times 9 \\\\\Rightarrow x=\dfrac{360\times 11}{9} = 440$

Men should be employed more= 440 -360 = 80

Hence, 80 men should be employed more to complete the work in 9 months
