Fraction of the remaining salary left
= 1 -
27 =
57 57 of the remaining salary =
38 of the total salary
5x37x3 of the remaining salary =
3x58x5 of the total salary
1521 of the remaining salary =
1540 of the total salary
Total salary = 40 u
Amount left = 15 u
Amount spent on the lamp = 21 u - 15 u = 6 u
Amount spent on the washing machine = 40 u - 15 u - 6 u = 19 u
19 u = 665
1 u = 665 ÷ 19 = 35
Her salary
= 40 u
= 40 x 35
= $1400
Answer(s): $1400
