can u please help me in getting the answer of beloq question
Is n an integer greater than 4?
(1) 3n is a positive integer.
(2) n/3 is a positive integer.

1 - insufficient. Take n=3, n=6. Both yield positive integers

2 - insufficient. Again, take n=3, n=6. Both satisfy condition but we cannot
confirm if n is > 4.

Together they are still insufficient. I'd say E

The given statement is asking if n > 4.

As you said, n = 3 OR 6 satisfies both statement 1 and 2.

if n=3, then n < 4, but
if n=6, then n > 4;

so we can't determine if n > 4. Answer E.

Statement (1) is insufficient because if n=1 then the answer is no and if n=4 then the answer is yes.

Statement (2) similarly is insufficient because if n=3 then the ans is no and if n=24 then the ans is yes.

We are left with C and E.

It cannot be C because if n=3 then one statement says yes and one statement says no.Hence E is the best answer.
