Hilda spent ¹₇ of her salary on a gas stove and ³₅ of the remainder on a kettle. If she saved the remaining $480, how much was her salary?
Fraction of the salary spent on the gas stove = ¹₇

Fraction of the salary on the remainder
= 1 - ¹₇
= ⁶₇

Fraction of the remainder on savings
= 1 - ³₅
= ²₅

Gas Stove	Remainder		Total
1x5	6x5		7x5
	Kettle	Savings
	3x6	2x6
5 u	18 u	12 u	35 u

The remainder and the total amount on the kettle and the savings are the same. Make the remainder and the total amount on the kettle and the savings the same.  LCM of 6 and 5 is 30.

Total salary = 35 u

Amount spent of the gas stove = 5 u
Amount spent on the kettle = 18 u
Amount of savings = 12 u

12 u = 480

1 u = 480 ÷ 12 = 40

Hilda's salary
= 35 u
= 35 x 40
= $1400

Answer(s): $1400
