New salary after it was increased by 20%
= 100% + 20%
= 120%
Increase in savings
= 20% x 10%
=
20100 x 10%
= 2%
New savings in percentage
= 10% + 2%
= 12%
12% of the original salary = 204
1% of the original salary = 204 ÷ 12 = 17
100% of the original salary = 100 x 17 = 1700
Harry's original salary = $1700
Answer(s): $1700
