New salary after it was increased by 40%
= 100% + 40%
= 140%
Increase in savings
= 40% x 25%
=
40100 x 25%
= 10%
New savings in percentage
= 25% + 10%
= 35%
35% of the original salary = 210
1% of the original salary = 210 ÷ 35 = 6
100% of the original salary = 100 x 6 = 600
John's original salary = $600
Answer(s): $600
