Japheth had grapefruits and chikoos. The ratio of grapefruits to chikoos was 8 : 3. After
14 of the grapefruits and 20 chikoos were sold, there were 6 times as many grapefruits as chikoos left. How many grapefruits and chikoos were sold?

Grapefruits |
Chikoos |
Comparing grapefruits
and chikoos at first |
8x1 =
8 u |
3x1 =
3 u |
| Before |
4x2 =
8 u |
|
| Change |
- 1x2 =
- 2 u |
- 20 |
| After |
3x2 =
6 u |
|
Comparing grapefruits
and chikoos in the end |
6 u |
1 u |
The number of grapefruits at first is repeated. Make the number of grapefruits at first the same. LCM of 8 and 4 is 8.
Number of chikoos sold
= 3 u - 1 u
= 2 u
2 u = 20
1 u = 20 ÷ 2 = 10
Number of grapefruits and chikoos sold
= 2 u + 20
= 2 x 10 + 20
= 20 + 20
= 40
Answer(s): 40
