The ratio of starfruits to chikoos is 3 : 7. If 12 chikoos are added, the ratio of starfruits to chikoos will be 3 : 11. How many less starfruits than chikoos are there in the end?
|
Starfruits |
Chikoos |
Before |
3 u |
7 u |
Change |
|
+ 12 |
After |
3 u |
11 u |
The number of starfruits at first and in the end remains unchanged.
Number of chikoos added
= 11 u - 7 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of less starfruits than chikoos in the end
= 11 u - 3 u
= 8 u
= 8 x 3
= 24
Answer(s): 24
