Risa spent ¹₇ of her salary on a kettle and ³₅ of the remainder on a gas stove. If she saved the remaining $360, how much was her salary?
Fraction of the salary spent on the kettle = ¹₇

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

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

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

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

Total salary = 35 u

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

12 u = 360

1 u = 360 ÷ 12 = 30

Risa's salary
= 35 u
= 35 x 30
= $1050

Answer(s): $1050
