Fraction of the remaining salary left
= 1 -
25 =
35 35 of the remaining salary =
17 of the total salary
3x15x1 of the remaining salary =
1x37x3 of the total salary
35 of the remaining salary =
321 of the total salary
Total salary = 21 u
Amount left = 3 u
Amount spent on the kettle = 5 u - 3 u = 2 u
Amount spent on the television = 21 u - 3 u - 2 u = 16 u
16 u = 720
1 u = 720 ÷ 16 = 45
Her salary
= 21 u
= 21 x 45
= $945
Answer(s): $945
