100% - 70% = 30%
YenMin =
30100 =
310 Combined salaries at first
= 3 u + 10 u
= 13 u
Increase in the combined salaries
= 40% x 13 u
=
40100 x 13 u
= 5.2 u
Combined salaries in the end
= 13 u + 5.2 u
= 18.2 u
18.2 u = 5096
1 u = 5096 ÷ 18.2 = 280
Min's salary before the increase
= 10 u
= 10 x 280
= $2800
Answer: $2800
