The population of a country increases by 8% in the first year, depreciates by 10% in the second year, and again increases by 6% in the third year. If the present population is 6 crore, find the population growth after 3 years.
Show answer & explanation
Correct answer: D
Explanation
The Correct answer is option 4 i.e. 18,19,200.
Given that
Present population = 6 crore = 60000000
In the first year, it increases by 8%
In the second year, it decreases by 10%
In the third year, it increases by 6%
According to the question;
After 3 years, Population = 60000000 × (108/100) × (90/100) × (106/100)
= 60 × 108 × 90 × 106 = 61819200
Hence, Population growth = 61819200 - 60000000 = 1819200
