Ethan had to collect some fruits from two marts and deliver some fruits to another mart. He collected from Mart H and the ratio of kiwis to persimmons was 3 : 4. When he reached Mart J, he unloaded
1112 of the persimmons and some kiwis from his vehicle. The ratio of kiwis to persimmons became 1 : 2. At Mart K, 37 kiwis and 24 persimmons were collected and the number of kiwis to persimmons became the same.
- How many fruits were there on his vehicle after visiting Mart K?
- How many kiwis were delivered to Mart J?

Comparing kiwis and persimmons at first |
Mart H |
3x6 = 18 u |
4x6 = 24 u |
Before 1 |
Mart H |
18 u |
12x2 = 24 u |
Change 1 |
Mart J |
- ? |
- 11x2 = - 22 u |
After 1 |
Mart K |
1 u |
1x2 = 2 u |
Before 2 |
Mart K |
1x1 = 1 u |
2x1 = 2 u |
Change 2 |
Mart K |
+ 37 |
+ 24 |
After 2 |
Mart K |
1 u + 37 |
2 u + 24 |
(a)
The number of persimmons after unloading at Mart J is repeated. Make the number of persimmons left after unloading at Mart J the same. LCM of 2 and 1 is 2.
The number of persimmons collected at Mart H is repeated. Make the number of persimmons collected at Mart H the same by multiplying 4 by 6.
The number of kiwis and persimmons in the end is the same.
2 u + 24 = 1 u + 37
2 u - 1 u = 37 - 24
1 u = 13
Number of kiwis on his vehicle after collecting from Mart K
= 1 u + 37
= 1 x 13 + 37
= 13 + 37
= 50
Number of fruits on his vehicle after collecting from Mart K
= 2 x 50
= 100
(b)
Number of kiwis delivered to Mart J
= 18 u - 1 u
= 17 u
= 17 x 13
= 221
Answer(s): (a) 100; (b) 221
