Answer 2

Concept

Percentage is a number or ratio that can be expressed as fraction of 100.

To calculate percentage of a number divide the number by the whole and then multiply it with 100.

Given

1) Salary increase of 5%

2) Salary After Increase HK$252000

Find

Salary before increase

Solution

Let the salary before increase be x

So ,

x + 5% of x = 252000

x + 5x/100 = 252000

105x = 252000 * 100

x = (252/105) * 1000 * 100

x = 2.4 * 1000 * 100

x = 240000

Jalina Salary before the increase was HK$240000.
