The ratio of pears to mangosteens is 5 : 7. If 28 mangosteens are added, the ratio of pears to mangosteens will be 5 : 11. How many more mangosteens than pears are there in the end?
| |
Pears |
Mangosteens |
| Before |
5 u |
7 u |
| Change |
|
+ 28 |
| After |
5 u |
11 u |
The number of pears at first and in the end remains unchanged.
Number of mangosteens added
= 11 u - 7 u
= 4 u
4 u = 28
1 u = 28 ÷ 4 = 7
Number of more mangosteens than pears in the end
= 11 u - 5 u
= 6 u
= 6 x 7
= 42
Answer(s): 42
