Nora had some persimmons and oranges in 2 cartons. In Carton D, the number of persimmons to the number of oranges was in the ratio of 3 : 8. In Carton E, there were twice as many persimmons as oranges. After Nora transferred
34 of the oranges from Carton D to Carton E, the number of fruits left in Carton D was 55 and the ratio of the number of persimmons to the number of oranges in Carton B became 7 : 9. How many fruits were in Carton E in the end?

Before |
3 u |
8 u |
2x7 = 14 p |
1x7 = 7 p |
Change |
|
- 6 u |
|
+ 6 u (+ 11 p) |
After |
3 u |
2 u |
7x2 = 14 p |
9x2 = 18 p |
Number of oranges that Nora transferred from Carton D to Carton E
=
34 x 8 u
= 6 u
Total number of fruits in Carton D in the end
= 3 u + 2 u
= 5 u
5 u = 55
1 u = 55 ÷ 5 = 11
The number of persimmons in Carton E is the unchanged quantity.
LCM of 2 and 7 is 14.
Number of oranges that Nora transferred from Carton D to Carton E
= 6 u
= 6 x 11
= 66
Increase in the number of oranges that due to the transfer from Carton D to Carton E
= 18 p - 7 p
= 11 p
11 p = 6 u
11 p = 66
1 p = 66 ÷ 11 = 6
Number of fruits in Carton E in the end
= 14 p + 18 p
= 32 p
= 32 x 6
= 192
Answer(s): 192
