Example 3:
Jasmine last month earned salary `$` 1250. He earned this month salary `$` 1600. Find how many percentage increases in her salary amount.

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.

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%
