Question

a number is increased by 25% and decreased by 20 % what is the change in that number​

Answer 1

Answer:

Let the number be 100.

Increased by 25% = 25/100 × 100 = 25

So number become = 100 + 25 = 125

Decreased by 20% = 20/100 × 125 = 25

Number become = 125 - 25 = 100

Means no change in number.

Answer 2

Answer:

no change at all

Step-by-step explanation:

increment

Let the number be 100

25% of 100 =25

100+25=125

decrement

20% of 125=25

125-25=100

Hence no change
