Pamela spent ¹₅ of her salary on a kettle and ³₅ of the remainder on a washing machine. If she saved the remaining $232, how much was her salary?
Fraction of the salary spent on the kettle = ¹₅

Fraction of the salary on the remainder
= 1 - ¹₅
= ⁴₅

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

Kettle	Remainder		Total
1x5	4x5		5x5
	Washing Machine	Savings
	3x4	2x4
5 u	12 u	8 u	25 u

The remainder and the total amount on the washing machine and the savings are the same. Make the remainder and the total amount on the washing machine and the savings the same.  LCM of 4 and 5 is 20.

Total salary = 25 u

Amount spent of the kettle = 5 u
Amount spent on the washing machine = 12 u
Amount of savings = 8 u

8 u = 232

1 u = 232 ÷ 8 = 29

Pamela's salary
= 25 u
= 25 x 29
= $725

Answer(s): $725
