There were 342 pomegranates and pears in a fruit stall.
37 of the pomegranates and
35 of pears were sold. Given that there were 156 pomegranates and pears left, how many pomegranates were there in the fruit stall at first?
| |
Pomegranates |
Pears |
| Before |
7 u |
5 p |
| Change |
- 3 u |
- 3 p |
| After |
4 u |
2 p |
7 u + 5 p = 342 --- (1)
4 u + 2 p = 156 --- (2)
Make p the same.
(1)
x 2 14 u + 10 p = 684 --- (3)
(2)
x 5 20 u + 10 p = 780 --- (4)
(4) - (3)
20 u - 14 u = 780 - 684
6 u = 96
1 u = 96 ÷ 6 = 16
Number of pomegranates at first
= 7 u
= 7 x 16
= 112
Answer(s): 112
