Answer:

The final answer is 160.

Step-by-step explanation:

Given,

We have a contractor who employed 560 people to complete a portion of a stadium in 9 months. He was asked to complete the same job in 7 months. We need to find the number of extra people required for the same task to be completed in 7 months.

Total number of people in the first set = 560

Total Time for first set = 9

Total number of people in the second set = x

Total Time for second set = 7

560 * 9 = x * 7

560 * 9 / 7 = x

x = 720

Total number of extra people = Number of people in second set - Number of people in first set = 720 - 560 = 160
