Question

A number is incresed by 10 % and then decresed by 10%. find the net increase or decrease percent

Answer 1

Answer:

1%

Step-by-step explanation:

Let the number is increased by 10%

x+ 10x/100 = 11x/10

The number is decreased by 10% =

11x/10− 11x/10 × 10/100

= 11x/10 - 11x/100 = 99x/100

Decrease in percentage is :

Decrease =x− 99x/100

​ = x/100

So, Decrease %

= x/100/x × 100%

= 1%
