Quantitative comparison questions are tricky because although you may be able to think of a situation when the value in Column A is greater that the value in Column B, if there is at least one scenario when Column B is greater than Column A or when the two values in the Columns are equal, then the answer must be that the relationship cannot be determined.
For example:
x is a non-negative integer.
|
| Column A |
Column B |
| x |
2x |
You might jump to the conclusion that the value in Column B is always greater than the value in Column A because regardless of what positive integer you substitute for x, Column B seems greater. However, you are told only that x is non-negative, so it can be 0, in which case Column A = Column B, because (2)(0) = 0. Therefore, because you can come up with a relationship when Columns A and B are equal and when Column B is greater than the value in Column A, then the relationship cannot be determined without additional information, so the answer is "cannot be determined".
