Fraction of the remaining salary left

25 =
35 35 of the remaining salary =
19 of the total salary
3x15x1 of the remaining salary =
1x39x3 of the total salary
35 of the remaining salary =
327 of the total salary
Total salary = 27 u
Amount left = 3 u
Amount spent on the lamp = 5 u - 3 u = 2 u
Amount spent on the television = 27 u - 3 u - 2 u = 22 u
22 u = 440
1 u = 440 ÷ 22 = 20
Her salary
= 27 u
= 27 x 20
= $540
Answer(s): $540
