There were 37 pomegranates and oranges in a stall at first. After

| Before |
5 u |
2 p |
37 |
| Change |
- 1 u |
- 1 p |
- 11 |
| After |
4 u |
1 p |
26 |
Total number of pomegranates and oranges sold
= 37 - 26
= 11
4 u + 1 p = 26
1 p = 26 - 4 u --- (1)
1 u + 1 p = 11
1 p = 11 - 1 u --- (2)
(2) = (1)
11 - 1 u = 26 - 4 u
4 u - 1 u = 26 - 11
3 u = 15
1 u = 15 ÷ 3 = 5
Number of pomegranates at first
= 5 u
= 5 x 5
= 25
Answer(s): 25
