The ratio of persimmons to peaches is 2 : 5. If 24 peaches are added, the ratio of persimmons to peaches will be 2 : 9. How many less persimmons than peaches are there in the end?

Persimmons |
Peaches |
| Before |
2 u |
5 u |
| Change |
|
+ 24 |
| After |
2 u |
9 u |
The number of persimmons at first and in the end remains unchanged.
Number of peaches added
= 9 u - 5 u
= 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Number of less persimmons than peaches in the end
= 9 u - 2 u
= 7 u
= 7 x 6
= 42
Answer(s): 42
