Finding the percentage of one number and another example problem
To finding the percentage of one number and another following formula used
Percentage formula = Changes in value x 100%
Original value
Example 1:
Find how much percentage increase from the number 80 to 95.5?

Example 2:
Find how much percentage decrease from the number 105 to 95.5?
Solution:
Decrease value = new value – old value
Decrease value = 95.5 – 105 = 9.5
Percentage decrease = `9.5/105` x100%
Decreased percentage = 9%
Example 3:
Jasmine last month earned salary `$` 1250. He earned this month salary `$` 1600. Find how many percentage increases in her salary amount.
Solution:
Jasmine increased salary = new salary – original salary
`$` 1600 –`$` 1250 = 350
Salary percentage increase = `350/1250` x100% = 28%
Jasmine increased salary percentage is 28%
Example 4:
Kishore last month earned salary `$` 1800. He earned this month salary `$` 1500. Find how much percentage decreased in his salary amount.
Solution:
Kishore decreased salary = new salary – original salary
`$` 1500 –`$` 1800 = 300
Salary percentage increase = `300/1800` x100%= 16.6%
Kishore decreases salary percentage is 16.6%
