1. The population of town increased from 1,75,000 to 2,62,500 in a decade. The average percentage increase of the population per year is --
- A. 4.7%
- B. 4.7%
- C. 4.7%
- D. 4.7%
Answer: Option B
Explanation:
The population increased in 10 years = 262500 - 175000 = 87500
The population increased in 1 years = 87500/10
Now, By 175000 peoples 1 years increased 8750
By 1 peoples 1 years increased = 8750/175000
By 100 peoples 1 years increased = ( 8750×100)/175000 = 5%
