Answer 1

HEY MATE HERE'S YOUR ANSWER

Let the original value of the number be x.
Now, Value after increase of 20% = 100+ 20%of 100
= 100+ 20 = 120
also, Value after decrease of 20 % = 120 - 20%of 120 = 96

Difference between the original and the final values = 100-96 = 4

Thus, the net decrease percent in the value of the number is 4%
