New income after it was increased by 40%
= 100% + 40%
= 140%
Increase in savings
= 40% x 5%
=
40100 x 5%
= 2%
New savings in percentage
= 5% + 2%
= 7%
7% of the original income = 182
1% of the original income = 182 ÷ 7 = 26
100% of the original income = 100 x 26 = 2600
Peter's original income = $2600
Answer(s): $2600
