The ratio of kiwis to passion fruits is 5 : 7. If 45 passion fruits are added, the ratio of kiwis to passion fruits will be 5 : 12. How many less kiwis than passion fruits are there in the end?
| |
Kiwis |
Passion Fruits |
| Before |
5 u |
7 u |
| Change |
|
+ 45 |
| After |
5 u |
12 u |
The number of kiwis at first and in the end remains unchanged.
Number of passion fruits added
= 12 u - 7 u
= 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Number of less kiwis than passion fruits in the end
= 12 u - 5 u
= 7 u
= 7 x 9
= 63
Answer(s): 63
