Seth had to collect some fruits from two markets and deliver some fruits to another market. He collected from Market V and the ratio of kiwis to pomegranates was 2 : 5. When he reached Market W, he unloaded
910 of the pomegranates and some kiwis from his vehicle. The ratio of kiwis to pomegranates became 3 : 4. At Market X, 57 kiwis and 50 pomegranates were collected and the number of kiwis to pomegranates became the same.
- How many fruits were there on his vehicle after visiting Market X?
- How many kiwis were delivered to Market W?

Comparing kiwis and pomegranates at first |
Market V |
2x8 = 16 u |
5x8 = 40 u |
Before 1 |
Market V |
16 u |
10x4 = 40 u |
Change 1 |
Market W |
- ? |
- 9x4 = - 36 u |
After 1 |
Market X |
3 u |
1x4 = 4 u |
Before 2 |
Market X |
3x1 = 3 u |
4x1 = 4 u |
Change 2 |
Market X |
+ 57 |
+ 50 |
After 2 |
Market X |
3 u + 57 |
4 u + 50 |
(a)
The number of pomegranates after unloading at Market W is repeated. Make the number of pomegranates left after unloading at Market W the same. LCM of 4 and 1 is 4.
The number of pomegranates collected at Market V is repeated. Make the number of pomegranates collected at Market V the same by multiplying 5 by 8.
The number of kiwis and pomegranates in the end is the same.
4 u + 50 = 3 u + 57
4 u - 3 u = 57 - 50
1 u = 7
Number of kiwis on his vehicle after collecting from Market X
= 3 u + 57
= 3 x 7 + 57
= 21 + 57
= 78
Number of fruits on his vehicle after collecting from Market X
= 2 x 78
= 156
(b)
Number of kiwis delivered to Market W
= 16 u - 3 u
= 13 u
= 13 x 7
= 91
Answer(s): (a) 156; (b) 91
