The ratio of chikoos to dragonfruits is 2 : 5. If 48 dragonfruits are added, the ratio of chikoos to dragonfruits will be 2 : 9. How many less chikoos than dragonfruits are there in the end?
| |
Chikoos |
Dragonfruits |
| Before |
2 u |
5 u |
| Change |
|
+ 48 |
| After |
2 u |
9 u |
The number of chikoos at first and in the end remains unchanged.
Number of dragonfruits added
= 9 u - 5 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Number of less chikoos than dragonfruits in the end
= 9 u - 2 u
= 7 u
= 7 x 12
= 84
Answer(s): 84
