New salary after it was increased by 20%
= 100% + 20%
= 120%
Increase in savings
= 20% x 15%
=
20100 x 15%
= 3%
New savings in percentage
= 15% + 3%
= 18%
18% of the original salary = 180
1% of the original salary = 180 ÷ 18 = 10
100% of the original salary = 100 x 10 = 1000
Ivan's original salary = $1000
Answer(s): $1000
