The ratio of peaches to persimmons is 5 : 7. If 8 persimmons are added, the ratio of peaches to persimmons will be 5 : 11. How many less peaches than persimmons are there in the end?

Peaches |
Persimmons |
| Before |
5 u |
7 u |
| Change |
|
+ 8 |
| After |
5 u |
11 u |
The number of peaches at first and in the end remains unchanged.
Number of persimmons added
= 11 u - 7 u
= 4 u
4 u = 8
1 u = 8 ÷ 4 = 2
Number of less peaches than persimmons in the end
= 11 u - 5 u
= 6 u
= 6 x 2
= 12
Answer(s): 12
