A farmer plants his vegetables in neat rows. He has 64 bean seedlings and plants 8 seedlings in a row. He also has 84 pumpkin seeds and plants 7 seeds in a row. Recently, he planted 48 radishes with 6 radishes in a row. If the farmer plants two rows per plant bed, how many plant beds did he have for all his plants?

There are 64 / 8 = 8 rows of bean seedlings.

There are 84 / 7 = 12 rows of pumpkin seedlings.

There are 48 / 6 = 8 rows of radishes.

Thus, there are a total of 8 + 12 + 8 = 28 rows of vegetables.

Therefore, the farmer had 28 / 2 = 14 plant beds.

The final answer: 14
