At a supermarket, there were
13 as many starfruits as guavas. After 2 starfruits and 32 guavas were sold, the number of starfruits became the same as the number of guavas. How many fruits were at the supermarket in the end?

Starfruits |
Guavas |
| Before |
1 u |
3 u |
| Change |
- 2 |
- 32 |
| After |
1 u - 2 |
3 u - 32 |
Number of starfruits and guavas in the end is the same.
3 u - 32 = 1 u - 2
3 u - 1 u = 32 - 2
2 u = 30
1 u = 30 ÷ 2 = 15
Number of fruits in the end
= 1 u - 2 + 3 u - 32
= 4 u - 34
= 4 x 15 - 34
= 60 - 34
= 26
Answer(s): 26
