Hi ankitbagla,
This question is worded in a slightly awkward way, but I believe that I've interpreted everything correctly. This DS question is perfect for TESTing VALUES.
We're given a specific sequence of numbers (6, 96, 996, etc.) We're asked if EVERY term is divisible by Q (if Q is even). This is a Yes/No question.
Fact 1: Q < 45
If Q = 2, then EVERY number is divisible (since they're all even). The answer to the question is YES.
If Q = 4, then 6 is NOT evenly divisible, but 96 IS evenly divisible. The answer to the question is NO.
Fact 1 is INSUFFICIENT
Fact 2: At least 2 terms are divisible by Q
If Q = 2, then EVERY number is divisible (since they're all even). The answer to the question is YES.
If Q = 4, then every number EXCEPT for 2 is divisible (96, 996, etc. are all divisible by 4). The answer to the question is NO.
Fact 2 is INSUFFICIENT
Combined, we have the exact same TEST values that overlap:
If Q = 2, then we have a YES
If Q = 4, then we have a NO.
Combined, INSUFFICIENT.
Final Answer: E
