100% + 70% = 170%
UshaPamela =
170100 =
1710 Combined salaries at first
= 17 u + 10 u
= 27 u
Decrease in the combined salaries
= 10% x 27 u
=
10100 x 27 u
= 2.7 u
Combined salaries in the end
= 27 u + 2.7 u
= 24.3 u
24.3 u = 5589
1 u = 5589 ÷ 24.3 = 230
Usha's salary before the decrease
= 17 u
= 17 x 230
= $3910
Answer: $3910
