Question

On the construction work of a flyover bridge there were 320 workers initially. The number of workers were increased by 25% every year. Find the number of workers after 2 years.

Answer 1

Answer:

The number of workers after 2 years = 500

Step-by-step explanation:

The problem is very much like that of compound interest

No. of workers after 2 years = Initial no. of workers(1 + rate/100)^2          

                                               = 320 × (1 + 25/100)^2

                                              = 320 × 25/16

                                             = 20 × 25 = 500

Therefore, the number of workers after 2 years = 500
