Answer 1

ANSWER: The income was changed by 1%

STEP BY STEP EXPLANATION:

Let the income of the person be x

If it is increased by 10%

Then,

The income will be x+10x/100

=x+0.1x

=1.1x

If it is decreased by 10%

Then,

The income will be 1.1x-1.1×10x/100

=1.1x-1.1×0.1x

=0.99x

Therefore change in income is given by

x-0. 99x

0.1x

so it was changed by 1%
