At a fruit stall, there were
13 as many apples as oranges. After 45 oranges were sold, the number of apples became
56 as many as the oranges. How many fruits were at the fruit stall at first?
| |
Apples |
Oranges |
| Before |
1x5 =
5 u |
3x5 =
15 u |
| Change |
|
- 45 |
| After |
5x1 =
5 u |
6x1 =
6 u |
The number of apples at first and in the end remains unchanged. Make the number of apples the same. LCM of 1 and 5 is 5.
Number of oranges sold
= 15 u - 6 u
= 9 u
9 u = 45
1 u = 45 ÷ 9 = 5
Number of fruits at first
= 5 u + 15 u
= 20 u
= 20 x 5
= 100
Answer(s): 100
