New income after it was decreased by 40%
= 100% - 40%
= 60%
Decrease in savings
= 40% x 15%
=
40100 x 15%
= 6%
New savings in percentage
= 15% - 6%
= 9%
9% of the original income = 180
1% of the original income = 180 ÷ 9 = 20
100% of the original income = 10 x 20 = 2000
Ian's original income = $2000
Answer(s): $2000
