There were 295 chikoos and mangoes in a fruit stall.
49 of the chikoos and
35 of mangoes were sold. Given that there were 132 chikoos and mangoes left, how many chikoos were there in the fruit stall at first?
|
Chikoos |
Mangoes |
Before |
9 u |
5 p |
Change |
- 4 u |
- 3 p |
After |
5 u |
2 p |
9 u + 5 p = 295 --- (1)
5 u + 2 p = 132 --- (2)
Make p the same.
(1)
x 2 18 u + 10 p = 590 --- (3)
(2)
x 5 25 u + 10 p = 660 --- (4)
(4) - (3)
25 u - 18 u = 660 - 590
7 u = 70
1 u = 70 ÷ 7 = 10
Number of chikoos at first
= 9 u
= 9 x 10
= 90
Answer(s): 90
