Sarah had some passion fruits and mangoes in 2 cartons. In Carton D, the number of passion fruits to the number of mangoes was in the ratio of 5 : 9. In Carton E, there were five times as many passion fruits as mangoes. After Sarah transferred
13 of the mangoes from Carton D to Carton E, the number of fruits left in Carton D was 418 and the ratio of the number of passion fruits to the number of mangoes in Carton B became 1 : 4. How many fruits were in Carton E in the end?

Before |
5 u |
9 u |
5x1 = 5 p |
1x1 = 1 p |
Change |
|
- 3 u |
|
+ 3 u (+ 19 p) |
After |
5 u |
6 u |
1x5 = 5 p |
4x5 = 20 p |
Number of mangoes that Sarah transferred from Carton D to Carton E
=
13 x 9 u
= 3 u
Total number of fruits in Carton D in the end
= 5 u + 6 u
= 11 u
11 u = 418
1 u = 418 ÷ 11 = 38
The number of passion fruits in Carton E is the unchanged quantity.
LCM of 5 and 1 is 5.
Number of mangoes that Sarah transferred from Carton D to Carton E
= 3 u
= 3 x 38
= 114
Increase in the number of mangoes that due to the transfer from Carton D to Carton E
= 20 p - 1 p
= 19 p
19 p = 3 u
19 p = 114
1 p = 114 ÷ 19 = 6
Number of fruits in Carton E in the end
= 5 p + 20 p
= 25 p
= 25 x 6
= 150
Answer(s): 150
