Question

on the consturction work of a flyover bridge there were 320 workers initiallly. the number of wokers were increased by 25% every year. find the number of workers after 2 years.

Answer 1

To calculate the number of workers after two years, we increment the initial number of 320 workers by 25% each year. After the first year, there are 400 workers, and after the second year, there are 500 workers.

Step-by-step explanation:

The question asks to calculate the number of workers on a construction site of a flyover bridge after 2 years, given that there were initially 320 workers and the number of workers increases by 25% every year.

To find the number of workers after the first year, we increase the initial number by 25%. So, we calculate 25% of 320 and then add it to the original 320 to get the number of workers after one year:

First year workers = Initial workers + (Initial workers × Percentage increase)

First year workers = 320 + (320 × 0.25)

First year workers = 320 + 80

First year workers = 400

Now, to find the number of workers after two years, we again increase the number of workers after the first year by 25%:

Second year workers = First year workers + (First year workers × Percentage increase)

Second year workers = 400 + (400 × 0.25)

Second year workers = 400 + 100

Second year workers = 500

Therefore, the number of workers on the construction site after 2 years will be 500.
