Question

A number is increased by 10% and then it is decresed by 10% .find the net incerese or decrease percent

Answer 1

the answer of this question will be increase in no.
let the no. be x
first we will increase x +10% of x
= x+ x/10
= 11x/10
now we will decrease

11x/10 - 10% of 11x/10
11x/10 - 11x/100
110x-11x/100
99x/100
x-99x/100
x/100
so there is a loss of no.
x/100 * 1/x * 100
= 1%
