Question

A no. Is first increased by 20 percent and the resulting no. is then decreased by 10 percent find the overall change in the no. as percent

Answer 1

The overall change is numer is = 8%gain

Step-by-step explanation:

• Let's assume that Number is = 100

• And it increase 20%

Increase in percentage = Number × percentage / 100

• =>100×20/100=20

Number after increase = increase in percentage+Number

• =>20+100=120

Now, it decreases by 10%

• 10% of 120 = 120×10/100=12

• New number after 10% decrease = 120-12=108

• Final number is = 108

• Which is 8% more than the actual number

Thus, the overall change in the number would be 8% gain.
