Fraction of the remaining salary left
= 1 -
38 =
58 58 of the remaining salary =
27 of the total salary
5x28x2 of the remaining salary =
2x57x5 of the total salary
1016 of the remaining salary =
1035 of the total salary
Total salary = 35 u
Amount left = 10 u
Amount spent on the lamp = 16 u - 10 u = 6 u
Amount spent on the laptop = 35 u - 10 u - 6 u = 19 u
19 u = 855
1 u = 855 ÷ 19 = 45
Her salary
= 35 u
= 35 x 45
= $1575
Answer(s): $1575
