There were 302 kiwis and pomegranates in a fruit stall.
27 of the kiwis and
38 of pomegranates were sold. Given that there were 190 kiwis and pomegranates left, how many kiwis were there in the fruit stall at first?
|
Kiwis |
Pomegranates |
Before |
7 u |
8 p |
Change |
- 2 u |
- 3 p |
After |
5 u |
5 p |
7 u + 8 p = 302 --- (1)
5 u + 5 p = 190 --- (2)
Make p the same.
(1)
x 5 35 u + 40 p = 1510 --- (3)
(2)
x 8 40 u + 40 p = 1520 --- (4)
(4) - (3)
40 u - 35 u = 1520 - 1510
5 u = 10
1 u = 10 ÷ 5 = 2
Number of kiwis at first
= 7 u
= 7 x 2
= 14
Answer(s): 14
