Options

• 2500

• 10000

• 252000

• 10100

Answer 1

10100

Explanation:

Present population = 250000

The rate at which it is increasing = 2%

T = 2 years

After 2-year population will be

`=250000[1+2/100]^2`

`=250000xx102/100xx102/100`

= 2,60,100

increase in population = 260100 − 250000
= 10100
