New salary after it was decreased by 30%
= 100% - 30%
= 70%
Decrease in savings
= 30% x 40%
=
30100 x 40%
= 12%
New savings in percentage
= 40% - 12%
= 28%
28% of the original salary = 112
1% of the original salary = 112 ÷ 28 = 4
100% of the original salary = 10 x 4 = 400
Henry's original salary = $400
Answer(s): $400
