Answer:
6 begonias
Explanation:
If there are twelve flowers in each vase
1st vase=9 daffodils+3 begonias
=12 flowers
2nd vase=twice as many begonias
If the florist put twice as many begonias in the 2nd vase, this could mean she put twice as many begonias in the 1st vase
Which is,
2 × 3 begonias in the 1st vase
=6 begonias
Therefore, second vase consist of 6 begonias and 6 daffodils
