There were 263 pomegranates and apples in a fruit stall.
310 of the pomegranates and
37 of apples were sold. Given that there were 158 pomegranates and apples left, how many pomegranates were there in the fruit stall at first?

Pomegranates |
Apples |
| Before |
10 u |
7 p |
| Change |
- 3 u |
- 3 p |
| After |
7 u |
4 p |
10 u + 7 p = 263 --- (1)
7 u + 4 p = 158 --- (2)
Make p the same.
(1)
x 4 40 u + 28 p = 1052 --- (3)
(2)
x 7 49 u + 28 p = 1106 --- (4)
(4) - (3)
49 u - 40 u = 1106 - 1052
9 u = 54
1 u = 54 ÷ 9 = 6
Number of pomegranates at first
= 10 u
= 10 x 6
= 60
Answer(s): 60
