The ratio of dragonfruits to starfruits is 3 : 5. If 18 starfruits are added, the ratio of dragonfruits to starfruits will be 3 : 8. How many more starfruits than dragonfruits are there in the end?
| |
Dragonfruits |
Starfruits |
| Before |
3 u |
5 u |
| Change |
|
+ 18 |
| After |
3 u |
8 u |
The number of dragonfruits at first and in the end remains unchanged.
Number of starfruits added
= 8 u - 5 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Number of more starfruits than dragonfruits in the end
= 8 u - 3 u
= 5 u
= 5 x 6
= 30
Answer(s): 30
