Its not clear.
From what I understand
So if the 2 statements don;t contradict each other, I shuold still test numbers considering B as an individual statement without have any bearing of A.
Please confirm if my understnading is right.
Yes. The two statements cannot contradict each other. But when analyzing one statement, you should as good as forget the previous one. (In some cases, one statement can give you an idea of what numbers you should try and hence be helpful but you will need to try others as well)
Take a simple example:
Is n divisible by 6?
1. n is even
2. n is a multiple of 3
When you try out statement 1, say, you try out 3 numbers: 2, 4, 6. You say 2 and 4 are not divisible by 6 but 6 is. So not sufficient.
When you try out statement 2, will you try only even multiples of 3? No. You will try all multiples of 3. 3 is not divisible by 6 but 6 is. Not sufficient. If you try only even multiples of 3, you will see that all even multiples of 3 are divisible by 6. So your answer will be 'sufficient'. But mind you, here you have used both statements together hence you will mark (C). So in essence, you did not analyze statement 2 alone at all. Answer could have been (B), we will never know (in the actual test!).
Hence, when analyzing each statement, do not look at the data of the other one. In fact, as far as possible, I try to re-read the question stem between the two statements to remind me of exactly what I have to consider and to help me forget the data I have already considered (else you might use it sub-consciously) Sometimes, one statement helps you cheat by giving you ideas of numbers you should try in addition to others, that's all.
