The ratio of pomegranates to mangosteens is 2 : 5. If 4 mangosteens are added, the ratio of pomegranates to mangosteens will be 2 : 7. How many more mangosteens than pomegranates are there in the end?
| |
Pomegranates |
Mangosteens |
| Before |
2 u |
5 u |
| Change |
|
+ 4 |
| After |
2 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 = 4
1 u = 4 ÷ 2 = 2
Number of more mangosteens than pomegranates in the end
= 7 u - 2 u
= 5 u
= 5 x 2
= 10
Answer(s): 10
