Question

A contractor has a work force of 480 men who can finish a certain piece of work in 10 months. How many extra men must be employed to complete the work in 8 months?​

Answer 1

Men is inversely proportional to Time(month)

Let,

Men be denoted by "M".

Months be denoted by "T".

| M | 480 | x(let) |

| T | 10 | 8 |

We know,

=> a= k

b

=> a×b= k(constant)

So,

=> 480 × 10 = x × 8

=>480×10 = x

8

=> x = 600

Therefore, 600 men will be required to complete the work in 8 months
