The population of a town increased from 1,75,000 to 2,62,500 in a decade. The average percent increase of population per year is:
4.37%
5%
6%
8.75%
Explanation:
Increase in 10 years = (262500 - 175000) = 87500.
Increase% =$ \left(\dfrac{875 00}{175000} \times 100\right) $% = 50%.
$\therefore$ Required average =$ \left(\dfrac{50}{10} \right) $% = 5%.
