Fraction of the remaining salary left

38 =
58 58 of the remaining salary =
19 of the total salary
5x18x1 of the remaining salary =
1x59x5 of the total salary
58 of the remaining salary =
545 of the total salary
Total salary = 45 u
Amount left = 5 u
Amount spent on the lamp = 8 u - 5 u = 3 u
Amount spent on the refrigerator = 45 u - 5 u - 3 u = 37 u
37 u = 1110
1 u = 1110 ÷ 37 = 30
Her salary
= 45 u
= 45 x 30
= $1350
Answer(s): $1350
