The ratio of grapefruits to chikoos is 5 : 7. If 50 chikoos are added, the ratio of grapefruits to chikoos will be 5 : 12. How many more chikoos than grapefruits are there in the end?
| |
Grapefruits |
Chikoos |
| Before |
5 u |
7 u |
| Change |
|
+ 50 |
| After |
5 u |
12 u |
The number of grapefruits at first and in the end remains unchanged.
Number of chikoos added
= 12 u - 7 u
= 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Number of more chikoos than grapefruits in the end
= 12 u - 5 u
= 7 u
= 7 x 10
= 70
Answer(s): 70
