Class V, W and X were given some caramel apples to sell for their charity drive. The average number of caramel apples the 3 classes had at first was 212. After Class W sold twice as many caramel apples as Class V and Class X sold ³₄ as many caramel apples as Class W, the average number of caramel apples the 3 classes had left was 47. How many caramel apples did Class V and Class X sell altogether?

Class V	Class W	Class X
1x2	2x2
	4x1	3x1
2 u	4 u	3 u

Class V : Class W : Class X
2 : 4 : 3

Total number of caramel apples that the 3 classes had at first
= 3 x 212
= 636

Number of caramel apples that the 3 classes left
= 3 x 47 
= 141

Number of caramel apples that were sold by 3 classes
= 636 - 141
= 495

2 u + 4 u + 3 u = 495
9 u = 495

1 u = 495 ÷ 9 = 55

Total number of caramel apples sold by Class V and Class X
= 2 u + 3 u
= 5 u
= 5 x 55
= 275

Answer(s): 275
