Example Questions on Percent Change

Question 1:
What is the percentage change from 60 to 72?
Solution:
Given that,
Old value = 60
New value = 72
The percent change formula is Percentage Change = [(New Value - Old Value)/Old Value] x 100%
Place the values in the formula
% change = [(72 - 60)/60] x 100
= [12/60] x 100
= [⅕] x 100
= 20
Therefore, the percentage change or percent increase is 20%.

Question 2:
What is the percent change from 10 to 6?
Solution:
Given that,
Old value = 10
New value = 6
The % change formula is Percentage Change = [(New Value - Old Value)/Old Value] x 100%
Percent change = [(6 - 10)/10] x 100%
= -[4/10] x 100%
= -[2/5] x 100%
= -2 x 20
= -40
Therefore, the percent change or percentage decrease is 40%.
