There were 244 pomegranates and chikoos in a fruit stall.
37 of the pomegranates and
35 of chikoos were sold. Given that there were 172 pomegranates and chikoos left, how many pomegranates were there in the fruit stall at first?
|
Pomegranates |
Chikoos |
Before |
7 u |
5 p |
Change |
- 3 u |
- 3 p |
After |
4 u |
2 p |
7 u + 5 p = 244 --- (1)
4 u + 2 p = 172 --- (2)
Make p the same.
(1)
x 2 14 u + 10 p = 488 --- (3)
(2)
x 5 20 u + 10 p = 860 --- (4)
(4) - (3)
20 u - 14 u = 860 - 488
6 u = 372
1 u = 372 ÷ 6 = 62
Number of pomegranates at first
= 7 u
= 7 x 62
= 434
Answer(s): 434
