New salary after it was decreased by 40%
= 100% - 40%
= 60%
Decrease in savings
= 40% x 25%
=
40100 x 25%
= 10%
New savings in percentage
= 25% - 10%
= 15%
15% of the original salary = 135
1% of the original salary = 135 ÷ 15 = 9
100% of the original salary = 10 x 9 = 900
Harry's original salary = $900
Answer(s): $900
