At a stall, there were
13 as many passion fruits as mangosteens. After 3 passion fruits and 17 mangosteens were sold, the number of passion fruits became the same as the number of mangosteens. How many fruits were at the stall in the end?

Passion Fruits |
Mangosteens |
| Before |
1 u |
3 u |
| Change |
- 3 |
- 17 |
| After |
1 u - 3 |
3 u - 17 |
Number of passion fruits and mangosteens in the end is the same.
3 u - 17 = 1 u - 3
3 u - 1 u = 17 - 3
2 u = 14
1 u = 14 ÷ 2 = 7
Number of fruits in the end
= 1 u - 3 + 3 u - 17
= 4 u - 20
= 4 x 7 - 20
= 28 - 20
= 8
Answer(s): 8
