Class G, H and J were given some lollipops to sell for their fund-raising project. The average number of lollipops the 3 classes had at first was 233. After Class H sold twice as many lollipops as Class G and Class J sold ³₄ as many lollipops as Class H, the average number of lollipops the 3 classes had left was 56. How many lollipops did Class G and Class J sell altogether?

Class G	Class H	Class J
1x2	2x2
	4x1	3x1
2 u	4 u	3 u

Class G : Class H : Class J
2 : 4 : 3

Total number of lollipops that the 3 classes had at first
= 3 x 233
= 699

Number of lollipops that the 3 classes left
= 3 x 56 
= 168

Number of lollipops that were sold by 3 classes
= 699 - 168
= 531

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

1 u = 531 ÷ 9 = 59

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

Answer(s): 295
