no change !

Answer 2

Answer:

0

Step-by-step explanation:

Let the number be X.

if the number is increased by 25%. New Number is 1.25X.

Now the number is decreased by 20%.

20% of 1.25X = 1.25X x 20% =  1.25X x 1/5 = 0.25 X

New Number - 1.25X - 0.25X = X

Since the old number and new number both are X, so there is no change in number.
