Class F, G and H were given some caramel apples to sell for their fund-raising project. The average number of caramel apples the 3 classes had at first was 207. After Class G sold twice as many caramel apples as Class F and Class H sold ⁴₅ as many caramel apples as Class G, the average number of caramel apples the 3 classes had left was 46. How many caramel apples did Class F and Class H sell altogether?

Class F	Class G	Class H
1x5	2x5
	5x2	4x2
5 u	10 u	8 u

Class F : Class G : Class H
5 : 10 : 8

Total number of caramel apples that the 3 classes had at first
= 3 x 207
= 621

Number of caramel apples that the 3 classes left
= 3 x 46 
= 138

Number of caramel apples that were sold by 3 classes
= 621 - 138
= 483

5 u + 10 u + 8 u = 483
23 u = 483

1 u = 483 ÷ 23 = 21

Total number of caramel apples sold by Class F and Class H
= 5 u + 8 u
= 13 u
= 13 x 21
= 273

Answer(s): 273
