n3 is an integer
3\n is an integer
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient

the fist statement says that 3*n is a integer ... there are 2 possiblities first n is an integer = 6 .. in which case 3*n is an intger .. second n is of the form a/3 ( a is an integer ) .. in which case again 3*n is an integer .. so first is insufficient ...
the second statement says 3/n is an integer .. there are again 2 possiblities .. first n=1 in which case n is an intger and so is 3/n .. second n is of the form 3/b (b is an integer ) .. in which case 3/n = 3/(3/b) = b an intger .. so again there is no defnite value for n .. so insufficient
now combibng both the cases .. we can see that n is an intger .. so the answer is C

Take the case of 3n = 6 then n=2 ,n integer
take the case of 3n=7 then n=7/3 , a non integer
2 is not sufficient
take the case when 3/n=1 then n=3,integer
take the case when 3/n =2 then n=3/2, a non integer
now combining both
Consider n=1/3, a non integer, it satisfies both I and II
Consider n=1, an integer , it satisfies both I and II
So, n can be an integer or a non integer
So E it is !!!
