Answer 2

Answer :-

• The person's salary is decreased by 4%.

Given :-

• The person's salary is increased by 20% and then it is decreased by 20%.

To find :-

• The person's salary in percent.

Solution :-

We know that the person's salary is increased by 20% and then decreased by 20%.

We are asked to find the salary of the person in percentage.

Let us assume the salary of person 100

The salary of person increased by 20%.

$\implies \sf 100 + 20 = 120$

Now, His salary decreased by 20%.

$\boxed{ \sf Total \: salary - Decreased \: salary = New \: salary}$

By applying the formula, We get :-

$\implies \sf 120 - \dfrac{20}{100} \times 120$

By simplifying, We get :-

$\implies \sf 120 - 24 = 96$

Now, we have to find difference in the salary.

$\boxed{ \sf Total \: salary - \frac{New \: salary }{100} \times 100 }$

$\implies \sf 100 - \dfrac{96}{100} \times 100$

$\implies \sf \dfrac{4}{100} \times 100$

$\implies \sf4 \%$

Therefore , The person's salary is decreased by 4%.
