At a fruit stall, there were
14 as many mangoes as oranges. After 20 oranges were sold, the number of mangoes became
23 as many as the oranges. How many fruits were at the fruit stall at first?
| |
Mangoes |
Oranges |
| Before |
1x2 =
2 u |
4x2 =
8 u |
| Change |
|
- 20 |
| After |
2x1 =
2 u |
3x1 =
3 u |
The number of mangoes at first and in the end remains unchanged. Make the number of mangoes the same. LCM of 1 and 2 is 2.
Number of oranges sold
= 8 u - 3 u
= 5 u
5 u = 20
1 u = 20 ÷ 5 = 4
Number of fruits at first
= 2 u + 8 u
= 10 u
= 10 x 4
= 40
Answer(s): 40
