The ratio of lemons to dragonfruits is 2 : 5. If 16 dragonfruits are added, the ratio of lemons to dragonfruits will be 2 : 7. How many more dragonfruits than lemons are there in the end?
| |
Lemons |
Dragonfruits |
| Before |
2 u |
5 u |
| Change |
|
+ 16 |
| After |
2 u |
7 u |
The number of lemons at first and in the end remains unchanged.
Number of dragonfruits added
= 7 u - 5 u
= 2 u
2 u = 16
1 u = 16 ÷ 2 = 8
Number of more dragonfruits than lemons in the end
= 7 u - 2 u
= 5 u
= 5 x 8
= 40
Answer(s): 40
