New salary after it was increased by 20%
= 100% + 20%
= 120%
Increase in savings
= 20% x 5%
=
20100 x 5%
= 1%
New savings in percentage
= 5% + 1%
= 6%
6% of the original salary = 186
1% of the original salary = 186 ÷ 6 = 31
100% of the original salary = 100 x 31 = 3100
Pierre's original salary = $3100
Answer(s): $3100
