Bryan had to collect some fruits from two marts and deliver some fruits to another mart. He collected from Mart S and the ratio of passion fruits to apples was 2 : 3. When he reached Mart T, he unloaded
34 of the apples and some passion fruits from his lorry. The ratio of passion fruits to apples became 2 : 3. At Mart U, 33 passion fruits and 14 apples were collected and the number of passion fruits to apples became the same.
- How many fruits were there on his lorry after visiting Mart U?
- How many passion fruits were delivered to Mart T?

Comparing passion fruits and apples at first |
Mart S |
2x4 = 8 u |
3x4 = 12 u |
Before 1 |
Mart S |
8 u |
4x3 = 12 u |
Change 1 |
Mart T |
- ? |
- 3x3 = - 9 u |
After 1 |
Mart U |
2 u |
1x3 = 3 u |
Before 2 |
Mart U |
2x1 = 2 u |
3x1 = 3 u |
Change 2 |
Mart U |
+ 33 |
+ 14 |
After 2 |
Mart U |
2 u + 33 |
3 u + 14 |
(a)
The number of apples after unloading at Mart T is repeated. Make the number of apples left after unloading at Mart T the same. LCM of 3 and 1 is 3.
The number of apples collected at Mart S is repeated. Make the number of apples collected at Mart S the same by multiplying 3 by 4.
The number of passion fruits and apples in the end is the same.
3 u + 14 = 2 u + 33
3 u - 2 u = 33 - 14
1 u = 19
Number of passion fruits on his lorry after collecting from Mart U
= 2 u + 33
= 2 x 19 + 33
= 38 + 33
= 71
Number of fruits on his lorry after collecting from Mart U
= 2 x 71
= 142
(b)
Number of passion fruits delivered to Mart T
= 8 u - 2 u
= 6 u
= 6 x 19
= 114
Answer(s): (a) 142; (b) 114
