Hi,
(1) -> if n=1,2,3. 222/n is integer.
if n=4, 222/n is not an integer.
Not sufficient

(2)-> if n=2, 222/n is integer.
if n=5, 222/n is not an integer.
Not sufficient

From(1)&(2) -> n=2,3. So, 222/n is integer
Sufficient
Hence, answer C

Cheers!

IMO C

IMO B

Since this is a yes/no question, we dont need to find the value of 222/n. We just need to check if the given condition helps to answer the question whether 222/n is an integer!

1) for n=1,2,3 222/n is integer
but for n=4 222/n is not an integer
hence we cant say definitely whether 222/n is integer

2) for n=2,3 222/n is integer
so with this second statement we can definitely say that 222/n is an integer,since we cannot contradict with any other value.

So correct answer is B

Correct me if my approach is wrong.

Hi,
That means you have already taken (1) implicitly.

You forgot to consider n=7 or other prime numbers..

ah yes..mu mistake..i took them together wrongly while analyzing statement 2. thanks all.
