The ratio of persimmons to lemons is 3 : 8. If 18 lemons are added, the ratio of persimmons to lemons will be 3 : 11. How many more lemons than persimmons are there in the end?
| |
Persimmons |
Lemons |
| Before |
3 u |
8 u |
| Change |
|
+ 18 |
| After |
3 u |
11 u |
The number of persimmons at first and in the end remains unchanged.
Number of lemons added
= 11 u - 8 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Number of more lemons than persimmons in the end
= 11 u - 3 u
= 8 u
= 8 x 6
= 48
Answer(s): 48
