Question

The population of Delhi is increasing at a rate of 4% per annum. If the current population of Delhi is 4500000, then the population after 3 years is

• A. 50,61,888
• B. 50,60,022
• C. 50,50,000

Answer 1

The correct option is A 50,61,888

P = 45,00,000
Rate of increasing = 4%
Time = 3 years
Therefore, the total population after 3 years will be
A = P × ${[1+\frac{R}{100}]}^n$
A = 45,00,000 × ${[1+\frac{4}{100}]}^3$
A = 45,00,000 × ${\left[\frac{104}{100}\right]}^3$
A = 50,61,888
