A fruit seller had chikoos and pomegranates. The ratio of chikoos to pomegranates was 3 : 7. After
35 of the chikoos and 17 pomegranates were sold, there were 3 times as many chikoos as pomegranates left. How many chikoos and pomegranates were there at first?
| |
Chikoos |
Pomegranates |
Total |
| Before |
3 u |
7 u |
10 u |
| Change |
- 1.8 u |
- 17 |
|
| After |
1.2 u |
3.6 u |
|
Number of chikoos sold
=
35 x 3 u
= 1.8 u
Number of chikoos left
= 3 u - 1.8 u
= 1.2 u
Number of pomegranates left
= 3 x 1.2 u
= 3.6 u
Number of pomegranates sold
= 7 u - 3.6 u
= 3.4 u
3.4 u = 17
1 u = 17 ÷ 3.4 = 5
Number of chikoos and pomegranates at first
= 3 u + 7 u
= 10 u
= 10 x 5
= 50
Answer(s): 50
