Question

A number is increased by 25%and decreased by 20% find thechange in that number

Answer 1

Answer:

No change

Step-by-step explanation:

Let x be the number.

New number after 25% increase = x * 125/100 = 1.25x.

New number after 20% decrease = 1.25x * 80/100 = x.

Thus increase/decrease = new final number - original number

                                         = x - x = 0.

Thus there is no change in the number.
