The ratio of persimmons to mangoes is 3 : 8. If 9 mangoes are added, the ratio of persimmons to mangoes will be 3 : 11. How many less persimmons than mangoes are there in the end?
| |
Persimmons |
Mangoes |
| Before |
3 u |
8 u |
| Change |
|
+ 9 |
| After |
3 u |
11 u |
The number of persimmons at first and in the end remains unchanged.
Number of mangoes added
= 11 u - 8 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Number of less persimmons than mangoes in the end
= 11 u - 3 u
= 8 u
= 8 x 3
= 24
Answer(s): 24
