Question

Find the percentage change, when a number is changed from:

6.25 to 7.50

Answer 1

Step: Find the percentage change
Given: Initial number = 6.25
Final number =7.50
$\therefore$ Change number = 7.50 - 6.25
= 1.25
Percentage change =$\frac{\text{Change in number}}{\text{Initial number}}\times 100$

$=\frac{1.25}{6.25}\times 100$

$=\frac{1}{5}\times$100

$=20$

Hence, the percentage change in number is 20%.
