The ratio of chikoos to dragonfruits is 3 : 5. If 15 dragonfruits are added, the ratio of chikoos to dragonfruits will be 3 : 10. How many more dragonfruits than chikoos are there in the end?
| |
Chikoos |
Dragonfruits |
| Before |
3 u |
5 u |
| Change |
|
+ 15 |
| After |
3 u |
10 u |
The number of chikoos at first and in the end remains unchanged.
Number of dragonfruits added
= 10 u - 5 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of more dragonfruits than chikoos in the end
= 10 u - 3 u
= 7 u
= 7 x 3
= 21
Answer(s): 21
