Pawan wants to plant 48 onion plants and 32 cabbage plants in his vegetable garden. What is the greatest number of rows possible if each row has the same number of onion plants and the same number of cabbage plants?

Answer: B. 16 rows

We need the highest common factor (HCF) of 48 and 32 so that each row has the same number of each vegetable.

Factors:
Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Factors of 32: 1, 2, 4, 8, 16, 32
The highest common factor is 16. So Pawan can make 16 rows.
Each row will have 48 ÷ 16 = 3 onion plants and 32 ÷ 16 = 2 cabbage plants
