Hi friends

Here is your answer

Let the number is 100

Now it is increase by 20%
 =  \frac{20}{100}  \times 100 \\  = 20
Number is 100+20 = 120

Now it is decrease by 20%
 =  \frac{20}{100}  \times 120 \\  = 24
Number is 120 - 24 = 96

Difference is 100 - 96 = 4

Net Decease% is
 =  \frac{4}{100}  \times 100 \\  \\  = 4\%
Hope it helps you
