New income after it was increased by 20%
= 100% + 20%
= 120%
Increase in savings
= 20% x 5%
=
20100 x 5%
= 1%
New savings in percentage
= 5% + 1%
= 6%
6% of the original income = 210
1% of the original income = 210 ÷ 6 = 35
100% of the original income = 100 x 35 = 3500
Julian's original income = $3500
Answer(s): $3500
