At a supermarket, there were
17 as many chikoos as mangosteens. After 3 chikoos and 27 mangosteens were sold, the number of chikoos became the same as the number of mangosteens. How many fruits were at the supermarket in the end?
| |
Chikoos |
Mangosteens |
| Before |
1 u |
7 u |
| Change |
- 3 |
- 27 |
| After |
1 u - 3 |
7 u - 27 |
Number of chikoos and mangosteens in the end is the same.
7 u - 27 = 1 u - 3
7 u - 1 u = 27 - 3
6 u = 24
1 u = 24 ÷ 6 = 4
Number of fruits in the end
= 1 u - 3 + 7 u - 27
= 8 u - 30
= 8 x 4 - 30
= 32 - 30
= 2
Answer(s): 2
