There were 243 apples and pomegranates in a fruit stall.
27 of the apples and
38 of pomegranates were sold. Given that there were 175 apples and pomegranates left, how many apples were there in the fruit stall at first?
|
Apples |
Pomegranates |
Before |
7 u |
8 p |
Change |
- 2 u |
- 3 p |
After |
5 u |
5 p |
7 u + 8 p = 243 --- (1)
5 u + 5 p = 175 --- (2)
Make p the same.
(1)
x 5 35 u + 40 p = 1215 --- (3)
(2)
x 8 40 u + 40 p = 1400 --- (4)
(4) - (3)
40 u - 35 u = 1400 - 1215
5 u = 185
1 u = 185 ÷ 5 = 37
Number of apples at first
= 7 u
= 7 x 37
= 259
Answer(s): 259
