Question

A number is increased from 125 to 150; find the percentage increase.

Answer 1

Step: Find percentage increase
Given: Intitial value = 125
Final value =150
$\therefore$ Increase in value = Final value - Initial value
= 150 - 125
=25
Percentage increase =$\frac{\text{Increased value}}{\text{Initial value}}\times 100$

$=\frac{25}{125}\times 100$

$=\frac{1}{2}\times 100$

$=20$

Hence, the percentage increase is 20%
