The ratio of starfruits to dragonfruits is 3 : 5. If 14 dragonfruits are added, the ratio of starfruits to dragonfruits will be 3 : 7. How many less starfruits than dragonfruits are there in the end?
| |
Starfruits |
Dragonfruits |
| Before |
3 u |
5 u |
| Change |
|
+ 14 |
| After |
3 u |
7 u |
The number of starfruits at first and in the end remains unchanged.
Number of dragonfruits added
= 7 u - 5 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Number of less starfruits than dragonfruits in the end
= 7 u - 3 u
= 4 u
= 4 x 7
= 28
Answer(s): 28
