The ratio of kiwis to mangosteens is 3 : 5. If 4 mangosteens are added, the ratio of kiwis to mangosteens will be 3 : 7. How many more mangosteens than kiwis are there in the end?
| |
Kiwis |
Mangosteens |
| Before |
3 u |
5 u |
| Change |
|
+ 4 |
| After |
3 u |
7 u |
The number of kiwis at first and in the end remains unchanged.
Number of mangosteens added
= 7 u - 5 u
= 2 u
2 u = 4
1 u = 4 ÷ 2 = 2
Number of more mangosteens than kiwis in the end
= 7 u - 3 u
= 4 u
= 4 x 2
= 8
Answer(s): 8
