Hi parulmahajan89,

Since Fact 2 focuses on numbers that are divided by 12, you have to be careful about your assumptions. While all numbers that are divisible by 12 ARE divisible by 6, the opposite is NOT true (a number that is divisible by 6 is not necessarily divisible by 12).

The numbers 6, 18, 30, etc. are NOT valid TEST Values for Fact 2.

You're absolutely right, parulmahajan89.
Data Sufficiency (DS) questions should yield the same values. In other words, DS questions will not contradict each other.

For example, the following would NEVER be a true DS question:
What is the value of x?
(1) 2x = 8
(2) x + 3 = 9
In this example, statement 1 tells us that x = 4 and statement 2 tells us that x = 6. Since these results contradict each other, this could never be a true DS question.

If you're interested, we have a free video titled "Useful Contradictions" that addresses what it means if you believe you've spotted a contradiction in a DS question: https://www.gmatprepnow.com/module/gmat- ... cy?id=1104
