New income after it was decreased by 10%
= 100% - 10%
= 90%
Decrease in savings
= 10% x 20%
=
10100 x 20%
= 2%
New savings in percentage
= 20% - 2%
= 18%
18% of the original income = 198
1% of the original income = 198 ÷ 18 = 11
100% of the original income = 10 x 11 = 1100
Rael's original income = $1100
Answer(s): $1100
