At a supermarket, there were
13 as many peaches as chikoos. After 7 peaches and 27 chikoos were sold, the number of peaches became the same as the number of chikoos. How many fruits were at the supermarket in the end?

Peaches |
Chikoos |
| Before |
1 u |
3 u |
| Change |
- 7 |
- 27 |
| After |
1 u - 7 |
3 u - 27 |
Number of peaches and chikoos in the end is the same.
3 u - 27 = 1 u - 7
3 u - 1 u = 27 - 7
2 u = 20
1 u = 20 ÷ 2 = 10
Number of fruits in the end
= 1 u - 7 + 3 u - 27
= 4 u - 34
= 4 x 10 - 34
= 40 - 34
= 6
Answer(s): 6
