The ratio of persimmons to guavas is 3 : 8. If 15 guavas are added, the ratio of persimmons to guavas will be 3 : 13. How many less persimmons than guavas are there in the end?
| |
Persimmons |
Guavas |
| Before |
3 u |
8 u |
| Change |
|
+ 15 |
| After |
3 u |
13 u |
The number of persimmons at first and in the end remains unchanged.
Number of guavas added
= 13 u - 8 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of less persimmons than guavas in the end
= 13 u - 3 u
= 10 u
= 10 x 3
= 30
Answer(s): 30
