Ryan had to collect some fruits from two marts and deliver some fruits to another mart. He collected from Mart R and the ratio of mangosteens to passion fruits was 2 : 3. When he reached Mart S, he unloaded
1112 of the passion fruits and some mangosteens from his lorry. The ratio of mangosteens to passion fruits became 3 : 4. At Mart T, 26 mangosteens and 24 passion fruits were collected and the number of mangosteens to passion fruits became the same.
- How many fruits were there on his lorry after visiting Mart T?
- How many mangosteens were delivered to Mart S?

Comparing mangosteens and passion fruits at first |
Mart R |
2x16 = 32 u |
3x16 = 48 u |
Before 1 |
Mart R |
32 u |
12x4 = 48 u |
Change 1 |
Mart S |
- ? |
- 11x4 = - 44 u |
After 1 |
Mart T |
3 u |
1x4 = 4 u |
Before 2 |
Mart T |
3x1 = 3 u |
4x1 = 4 u |
Change 2 |
Mart T |
+ 26 |
+ 24 |
After 2 |
Mart T |
3 u + 26 |
4 u + 24 |
(a)
The number of passion fruits after unloading at Mart S is repeated. Make the number of passion fruits left after unloading at Mart S the same. LCM of 4 and 1 is 4.
The number of passion fruits collected at Mart R is repeated. Make the number of passion fruits collected at Mart R the same by multiplying 3 by 16.
The number of mangosteens and passion fruits in the end is the same.
4 u + 24 = 3 u + 26
4 u - 3 u = 26 - 24
1 u = 2
Number of mangosteens on his lorry after collecting from Mart T
= 3 u + 26
= 3 x 2 + 26
= 6 + 26
= 32
Number of fruits on his lorry after collecting from Mart T
= 2 x 32
= 64
(b)
Number of mangosteens delivered to Mart S
= 32 u - 3 u
= 29 u
= 29 x 2
= 58
Answer(s): (a) 64; (b) 58
