Question

the population of town is 121000 . if it is decreasing at the rate of 10% every year . find its population after 2 year​

Answer 1

Answer:

98,010

Step-by-step explanation:

Present population of town (P) = 121000

Rate (R) = 10%

Time (n) = 2 years

Let the population after 2 years be x.

=> x = P (1 - R/100)²

=> x = 121000 (1 - 10/100)²

=> x = 121000 (9/10) (9/10)

=> x = 98,010

Therefore, the population after 2 years will be 98,010.
