1. N could be any multiple of 2,3,6. Insufficient.
2. Insufficient.

Combined,
There is only 1 multiple of 2,3,6 b/w 30 and 70. Sufficient.

If N is a multiple of 2, 3 and 6, then N is a multiple of 6 (every multiple of 6 is also a multiple of 2 and 3). There are several multiples of 6 between 30 and 70, so the answer is E; N could be 36 or N could be 42, for example.

If by Statement 1 the intended meaning is "N is a multiple of 2*3*6", then the question is badly worded.
