The population of a city increases 11% annually. Find the net percentage increase in twoyears.

Correct option is A

Given:

Annual increase rate = 11%

Time = 2 years

Formula Used:

Net % Increase = $$a + b + \frac{ab}{100}$$​​

Solution:

Here, a = 11%, b = 11%

Net % Increase = $$11 + 11 + \frac{11 \times 11}{100}$$​​

​$$= 22 + \frac{121}{100}$$​​

= 22 + 1.21

= 23.21%
