At a stall, there were
13 as many pomegranates as dragonfruits. After 4 pomegranates and 32 dragonfruits were sold, the number of pomegranates became the same as the number of dragonfruits. How many fruits were at the stall in the end?

Pomegranates |
Dragonfruits |
| Before |
1 u |
3 u |
| Change |
- 4 |
- 32 |
| After |
1 u - 4 |
3 u - 32 |
Number of pomegranates and dragonfruits in the end is the same.
3 u - 32 = 1 u - 4
3 u - 1 u = 32 - 4
2 u = 28
1 u = 28 ÷ 2 = 14
Number of fruits in the end
= 1 u - 4 + 3 u - 32
= 4 u - 36
= 4 x 14 - 36
= 56 - 36
= 20
Answer(s): 20
