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.

User
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 answer: 14.
