The ratio of dragonfruits to persimmons is 3 : 8. If 40 persimmons are added, the ratio of dragonfruits to persimmons will be 3 : 13. How many more persimmons than dragonfruits are there in the end?
| |
Dragonfruits |
Persimmons |
| Before |
3 u |
8 u |
| Change |
|
+ 40 |
| After |
3 u |
13 u |
The number of dragonfruits at first and in the end remains unchanged.
Number of persimmons added
= 13 u - 8 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of more persimmons than dragonfruits in the end
= 13 u - 3 u
= 10 u
= 10 x 8
= 80
Answer(s): 80
