At a fruit stall, there were
13 as many oranges as chikoos. After 15 chikoos were sold, the number of oranges became
34 as many as the chikoos. How many fruits were at the fruit stall at first?
|
Oranges |
Chikoos |
Before |
1x3 = 3 u |
3x3 = 9 u |
Change |
|
- 15 |
After |
3x1 = 3 u |
4x1 = 4 u |
The number of oranges at first and in the end remains unchanged. Make the number of oranges the same. LCM of 1 and 3 is 3.
Number of chikoos sold
= 9 u - 4 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of fruits at first
= 3 u + 9 u
= 12 u
= 12 x 3
= 36
Answer(s): 36
