New salary after it was increased by 40%
= 100% + 40%
= 140%
Increase in savings
= 40% x 15%
=
40100 x 15%
= 6%
New savings in percentage
= 15% + 6%
= 21%
21% of the original salary = 189
1% of the original salary = 189 ÷ 21 = 9
100% of the original salary = 100 x 9 = 900
Ethan's original salary = $900
Answer(s): $900
