We can solve this question using matching operations
Given:
Quantity A: 5ab
Quantity B: 10ab
Since a is POSITIVE, we can safely divide both quantities by a to get:
Quantity A: 5b
Quantity B: 10b
We can also safely divide both quantities by 5 to get:
Quantity A: b
Quantity B: 2b
Finally, let's subtract b from both quantities to get:
Quantity A: 0
Quantity B: b
Since b could be positive, negative or zero, the correct answer is D

ab or 5 ab (simplified), which one is greatest ??
we do not have any information about b. The two statements are not sufficient to determine which one is the biggest.
The answer is D
