100% - 50% = 50%
FannyIrene =
50100 =
12 Combined salaries at first
= 1 u + 2 u
= 3 u
Increase in the combined salaries
= 60% x 3 u
=
60100 x 3 u
= 1.8 u
Combined salaries in the end
= 3 u + 1.8 u
= 4.8 u
4.8 u = 1008
1 u = 1008 ÷ 4.8 = 210
Irene's salary before the increase
= 2 u
= 2 x 210
= $420
Answer: $420
