Question

a number increased by 10% then decreased by 10% find the decrease/ increase​

Answer 1

Answer:

decrease by 1 percent

Step-by-step explanation:

consider a number, let us take 100

this number is increased by 10 percent so 10 percent of 100 is 10 so the number becomes 110

and then this number is decreased by 10 percent now the 10 percent of 110 is 11 so the number becomes 110-11=99

the actual number was 100 after increasing by 10 percent and decreasing by 10 percent it becomes 99 so it is decresed by 1 percent
