Quantitative Comparison Practice Test 4

Concept:Compare the two expressions by checking whether their relative size is fixed for all possible values of $x$ and $y$.Explanation:Column A is $20\%$ of $x = 0.2x$.Column B is $10\%$ of $y = 0.1y$.No relation between $x$ and $y$ is given.If $x = 100$ and $y = 100$, then $A = 20$ and $B = 10$, so Column A is greater.If $x = 10$ and $y = 100$, then $A = 2$ and $B = 10$, so Column B is greater.Since the comparison changes with different values, the relationship cannot be determined.Answer:The relationship cannot be determined from the information given.
