100% - 70% = 30%
UshaKylie =
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 = 4914
1 u = 4914 ÷ 18.2 = 270
Kylie's salary before the increase
= 10 u
= 10 x 270
= $2700
Answer: $2700
