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.
