Question

A number increases by 10%, and then decreases by 10%. Will the result be greater than, less than, or equal to the original number?

Answer 1

Hey there! The answer would be less than because 10% of the first number would be more than 10% of the second number. If you don't know what I mean then look at this as a example. 100*0.10=10, of you subtract 100 by 10 you get 90, 90*0.10=9, you add 90 by 9 you get 99, 99 is less than 100 (99<100). Do you see what I mean. If not feel free to message me. :)

Answer 2

One way it so try

100
increase by 10%
10% of 100=10 so 100+10=110

then decrease by 10%
10% of 110=11 so 110-11=99

original number=100
is 99 greater than or less or equal the original?
99<100
it is less
