Example 1: There are 200 students in a class. Out of them, 90 are girls. Find the percentage of girls in the class.
Solution: We are given,
Total students in the class=200
Girls in the class = 90
Percentage of girls in the class = (Girls in the class⁄ Total no. of students) × 100
Percentage of girls in the class = (90/200)x100 = 45%
Example 2: The price of a $1.50 candy bar is increased by 25%. Calculate the new price.
Solution: We are given,
Price of the Candy= $1.50
Increase in the price of candy= 25% or 25/100
New Price of candy= Old Price + increase in price
New Price of candy= 1.50 +25/100
New Price of candy= 1.50 + 1.50 ×.25
New Price of candy= $ 1.875
Example 3: Radha earns a monthly salary of $1200. She spends $280/month on food. What percent of the monthly salary does she save?
Solution: Monthly salary of Radha= $1200
Salary saved by Radha = $(1200 – 280) = $920
The fraction of salary she saves = 920/1200
Percentage of salary she saves = (920/1200)×100 = 920/12 = 76.667 %
