Billy had chikoos and passion fruits. The ratio of chikoos to passion fruits was 8 : 7. After
34 of the chikoos and 30 passion fruits were sold, there were 2 times as many chikoos as passion fruits left. How many chikoos and passion fruits were there at first?

Chikoos |
Passion Fruits |
Comparing chikoos
and passion fruits at first |
8x1 =
8 u |
7x1 =
7 u |
| Before |
4x2 =
8 u |
|
| Change |
- 3x2 =
- 6 u |
- 30 |
| After |
1x2 =
2 u |
|
Comparing chikoos
and passion fruits in the end |
2 u |
1 u |
The number of chikoos at first is repeated. Make the number of chikoos at first the same. LCM of 8 and 4 is 8.
Number of passion fruits sold
= 7 u - 1 u
= 6 u
6 u = 30
1 u = 30 ÷ 6 = 5
Number of chikoos and passion fruits at first
= 8 u + 7 u
= 15 u
= 15 x 5
= 75
Answer(s): 75
