Mark had kiwis and pomegranates. The ratio of kiwis to pomegranates was 6 : 5. After
12 of the kiwis and 12 pomegranates were sold, there were 3 times as many kiwis as pomegranates left. How many kiwis and pomegranates were sold?
| |
Kiwis |
Pomegranates |
Comparing kiwis
and pomegranates at first |
6x1 =
6 u |
5x1 =
5 u |
| Before |
2x3 =
6 u |
|
| Change |
- 1x3 =
- 3 u |
- 12 |
| After |
1x3 =
3 u |
|
Comparing kiwis
and pomegranates in the end |
3 u |
1 u |
The number of kiwis at first is repeated. Make the number of kiwis at first the same. LCM of 6 and 2 is 6.
Number of pomegranates sold
= 5 u - 1 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of kiwis and pomegranates sold
= 3 u + 12
= 3 x 3 + 12
= 9 + 12
= 21
Answer(s): 21
