Class A, B and C were given some lollipops to sell for their donation drive. The average number of lollipops the 3 classes had at first was 232. After Class B sold twice as many lollipops as Class A and Class C sold ³₄ as many lollipops as Class B, the average number of lollipops the 3 classes had left was 55. How many lollipops did Class A and Class C sell altogether?

Class A	Class B	Class C
1x2	2x2
	4x1	3x1
2 u	4 u	3 u

Class A : Class B : Class C
2 : 4 : 3

Total number of lollipops that the 3 classes had at first
= 3 x 232
= 696

Number of lollipops that the 3 classes left
= 3 x 55 
= 165

Number of lollipops that were sold by 3 classes
= 696 - 165
= 531

2 u + 4 u + 3 u = 531
9 u = 531

1 u = 531 ÷ 9 = 59

Total number of lollipops sold by Class A and Class C
= 2 u + 3 u
= 5 u
= 5 x 59
= 295

Answer(s): 295
