Class T, U and V were given some caramel apples to sell for their donation drive. The average number of caramel apples the 3 classes had at first was 244. After Class U sold twice as many caramel apples as Class T and Class V sold
34 as many caramel apples as Class U, the average number of caramel apples the 3 classes had left was 46. How many caramel apples did Class T and Class V sell altogether?
Class T |
Class U |
Class V |
1x2 |
2x2 |
|
|
4x1 |
3x1 |
2 u |
4 u |
3 u |
Class T : Class U : Class V
2 : 4 : 3
Total number of caramel apples that the 3 classes had at first
= 3 x 244
= 732
Number of caramel apples that the 3 classes left
= 3 x 46
= 138
Number of caramel apples that were sold by 3 classes
= 732 - 138
= 594
2 u + 4 u + 3 u = 594
9 u = 594
1 u = 594 ÷ 9 = 66
Total number of caramel apples sold by Class T and Class V
= 2 u + 3 u
= 5 u
= 5 x 66
= 330
Answer(s): 330
