New salary after it was increased by 20%
= 100% + 20%
= 120%
Increase in savings
= 20% x 25%
=
20100 x 25%
= 5%
New savings in percentage
= 25% + 5%
= 30%
30% of the original salary = 210
1% of the original salary = 210 ÷ 30 = 7
100% of the original salary = 100 x 7 = 700
Tim's original salary = $700
Answer(s): $700
