A fruit seller had chikoos and mangosteens. The ratio of chikoos to mangosteens was 2 : 9. After
14 of the chikoos and 108 mangosteens were sold, there were 2 times as many chikoos as mangosteens left. How many chikoos and mangosteens were there at first?
|
Chikoos |
Mangosteens |
Total |
Before |
2 u |
9 u |
11 u |
Change |
- 0.5 u |
- 108 |
|
After |
1.5 u |
3 u |
|
Number of chikoos sold
=
14 x 2 u
= 0.5 u
Number of chikoos left
= 2 u - 0.5 u
= 1.5 u
Number of mangosteens left
= 2 x 1.5 u
= 3 u
Number of mangosteens sold
= 9 u - 3 u
= 6 u
6 u = 108
1 u = 108 ÷ 6 = 18
Number of chikoos and mangosteens at first
= 2 u + 9 u
= 11 u
= 11 x 18
= 198
Answer(s): 198
