akash's salary in 2014 was 25% more than that of 2013, then his previous salary was what % of present salary

80%

Step-by-step explanation:

Focus on the important parts of the problem:

The present salary is 25% more than the previous salary.

previous = % of present?

Use a mock/fake situation. Let' say the previous salary is $100.

100 = % of present

Present salary is $100 increased by 25%.

$100 X 1.25 = $125

100 = % of 125

Solve this in decimal form (convert it to a percentage later).

Let x be the percentage in decimal form.

100 = 125x

100/125 = x Isolate "x" by dividing by sides by 125

x = 0.80

Convert 0.80 to percentage by multiplying by 100.

0.80 X 100 = 80%

When comparing two things using percentage, 100% is the same. Less than 100% is less and more than 100% is more.

Since his previous salary was less than his present salary, this answer makes sense.

Therefore his previous salary was 80% of his present salary.

2014 salary = 125 of 2013 salary

Therefore if 2013 salary is 100, 2014 salary is 125

x% of 125 = 100

125x/100 = 100

x = 100*100/125

x = 80

His previous salary is 80% of his present salary
