Fraction of the remaining salary left
= 1 -
16 =
56 56 of the remaining salary =
38 of the total salary
5x36x3 of the remaining salary =
3x58x5 of the total salary
1518 of the remaining salary =
1540 of the total salary
Total salary = 40 u
Amount left = 15 u
Amount spent on the lamp = 18 u - 15 u = 3 u
Amount spent on the laptop = 40 u - 15 u - 3 u = 22 u
22 u = 550
1 u = 550 ÷ 22 = 25
Her salary
= 40 u
= 40 x 25
= $1000
Answer(s): $1000
