Class F, G and H were given some lollipops to sell for their charity drive. The average number of lollipops the 3 classes had at first was 208. After Class G sold four times as many lollipops as Class F and Class H sold ⁴₅ as many lollipops as Class G, the average number of lollipops the 3 classes had left was 44. How many lollipops did Class F and Class H sell altogether?

Class F	Class G	Class H
1x5	4x5
	5x4	4x4
5 u	20 u	16 u

Class F : Class G : Class H
5 : 20 : 16

Total number of lollipops that the 3 classes had at first
= 3 x 208
= 624

Number of lollipops that the 3 classes left
= 3 x 44 
= 132

Number of lollipops that were sold by 3 classes
= 624 - 132
= 492

5 u + 20 u + 16 u = 492
41 u = 492

1 u = 492 ÷ 41 = 12

Total number of lollipops sold by Class F and Class H
= 5 u + 16 u
= 21 u
= 21 x 12
= 252

Answer(s): 252
