The ratio of pomegranates to mangosteens is 3 : 5. If 6 mangosteens are added, the ratio of pomegranates to mangosteens will be 3 : 7. How many more mangosteens than pomegranates are there in the end?
| |
Pomegranates |
Mangosteens |
| Before |
3 u |
5 u |
| Change |
|
+ 6 |
| After |
3 u |
7 u |
The number of pomegranates at first and in the end remains unchanged.
Number of mangosteens added
= 7 u - 5 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Number of more mangosteens than pomegranates in the end
= 7 u - 3 u
= 4 u
= 4 x 3
= 12
Answer(s): 12
