Vanessa spent ¹₆ of her salary on a food processor and ²₃ of the remainder on a lamp. If she saved the remaining $200, how much was her salary?
Fraction of the salary spent on the food processor = ¹₆

Fraction of the salary on the remainder
= 1 - ¹₆
= ⁵₆

Fraction of the remainder on savings
= 1 - ²₃
= ¹₃

Food Processor	Remainder		Total
1x3	5x3		6x3
	Lamp	Savings
	2x5	1x5
3 u	10 u	5 u	18 u

The remainder and the total amount on the lamp and the savings are the same. Make the remainder and the total amount on the lamp and the savings the same.  LCM of 5 and 3 is 15.

Total salary = 18 u

Amount spent of the food processor = 3 u
Amount spent on the lamp = 10 u
Amount of savings = 5 u

5 u = 200

1 u = 200 ÷ 5 = 40

Vanessa's salary
= 18 u
= 18 x 40
= $720

Answer(s): $720
