If k is an integer and 2 < k < 8, what is the value of k ?

(1) k is a factor of 30.
(2) k is a factor of 12

The answer given is E.

from statement 1 : k can be 2,3,5. k>2, so 3 or 5. NS
from statement 2 : k can be 2,3. k>2, so 3. Sufficient

Hence my answer was B. Am i missing something :(

You probably misunderstood and worked for only primes.
The question stem states integers.

from statement 1 : Factors of 30 that are between 2 and 8 are: 3, 5 and 6. Not Sufficient

from statement 2: Factors of 12 that are between 2 and 8 are: 3 and 6. Not Sufficient

Both taken together: k can be either 3 or 6. Not Sufficient.

You missed 6.
Hope that helps.

St I k= 3,5,6 insufficient
St II k = 3,4,6 insufficient
St I and II k = 3, 6 insufficient

Hence Option E is correct

1. K is a factor of 30.
2. K is a factor of 12.

Is B incorrect since Q mentions about factors (ie no when divided by factor will leave remainder as zero)
and not prime factors (B's distinct prime factors shall be 2 and 3) Since only 3 falls in range
given by Q, B would have been correct answer choice.

Yes. The factors of 12 are 1, 2, 3, 4, 6, and 12. While prime factors of 12 are 2 and 3.
