1) N can take multiple values. Yes and No. Not Sufficient.
2) N is an even integer. Yes (12) and No (4). Not Sufficient.
1) & 2) together - Still not sufficient.
E is the correct answer.

If N is a positive integer, is N divisible by 12?

(1) N is divisible by 6.
(2) N is divisible by 2.

The question is asking if N has 2^2 and 3^1 as its prime factors ?

1) That means N has at least 2^1 and 3^1 as its prime factors but we don't know anything else that could help us answer the question.

Insufficient.

BCE

2) N has at least 2^1.
Insufficient.

Both the statements:
Statement 1: N is divisible by 6 that means it is divisible by 2 and 3.
Statement 2: N is divisible by 2 (this information we already have from statement 1).

The answer is E.
