Fraction of the remaining salary left
= 1 -
38 =
58 58 of the remaining salary =
29 of the total salary
5x28x2 of the remaining salary =
2x59x5 of the total salary
1016 of the remaining salary =
1045 of the total salary
Total salary = 45 u
Amount left = 10 u
Amount spent on the lamp = 16 u - 10 u = 6 u
Amount spent on the refrigerator = 45 u - 10 u - 6 u = 29 u
29 u = 1015
1 u = 1015 ÷ 29 = 35
Her salary
= 45 u
= 45 x 35
= $1575
Answer(s): $1575
