At a fruit stall, there were
15 as many pomegranates as pears. After 21 pears were sold, the number of pomegranates became
23 as many as the pears. How many fruits were at the fruit stall at first?
| |
Pomegranates |
Pears |
| Before |
1x2 =
2 u |
5x2 =
10 u |
| Change |
|
- 21 |
| After |
2x1 =
2 u |
3x1 =
3 u |
The number of pomegranates at first and in the end remains unchanged. Make the number of pomegranates the same. LCM of 1 and 2 is 2.
Number of pears sold
= 10 u - 3 u
= 7 u
7 u = 21
1 u = 21 ÷ 7 = 3
Number of fruits at first
= 2 u + 10 u
= 12 u
= 12 x 3
= 36
Answer(s): 36
