4 u |
2 p |

| Change |
- 1 u |
- 1 p |
- 25 |
| After |
3 u |
1 p |
51 |
Total number of pomegranates and lemons sold
= 76 - 51
= 25
3 u + 1 p = 51
1 p = 51 - 3 u --- (1)
1 u + 1 p = 25
1 p = 25 - 1 u --- (2)
(2) = (1)
25 - 1 u = 51 - 3 u
3 u - 1 u = 51 - 25
2 u = 26
1 u = 26 ÷ 2 = 13
Number of pomegranates at first
= 4 u
= 4 x 13
= 52
Answer(s): 52
