The ratio of dragonfruits to starfruits is 2 : 5. If 24 starfruits are added, the ratio of dragonfruits to starfruits will be 2 : 7. How many more starfruits than dragonfruits are there in the end?
| |
Dragonfruits |
Starfruits |
| Before |
2 u |
5 u |
| Change |
|
+ 24 |
| After |
2 u |
7 u |
The number of dragonfruits at first and in the end remains unchanged.
Number of starfruits added
= 7 u - 5 u
= 2 u
2 u = 24
1 u = 24 ÷ 2 = 12
Number of more starfruits than dragonfruits in the end
= 7 u - 2 u
= 5 u
= 5 x 12
= 60
Answer(s): 60
