Fraction of the remaining salary left
= 1 -
15 =
45 45 of the remaining salary =
37 of the total salary
4x35x3 of the remaining salary =
3x47x4 of the total salary
1215 of the remaining salary =
1228 of the total salary
Total salary = 28 u
Amount left = 12 u
Amount spent on the kettle = 15 u - 12 u = 3 u
Amount spent on the washing machine = 28 u - 12 u - 3 u = 13 u
13 u = 325
1 u = 325 ÷ 13 = 25
Her salary
= 28 u
= 28 x 25
= $700
