If \(N = 1234@\) and @ represents the units digit, is N a multiple of 5?

(1) @! is not divisible by 5
(2) @ is divisible by 9

My understanding is that if @! is not divisible by 5 then @ is less than 5 so not divisible by 5

and since @ is divisible by 9, it is not divisible by 5, since 9 is a prime number, so i picked D. but the OA is something else .can some one please explain. Thank you


I got this question on the GMAT club test today and I thought '!' is just another character like '@' . How cool is that? :D Otherwise I got the other finer nuances :D

Can someone plz explain to me the concept of Combining two option (By integration), How when by using first option we get @=0,1,2,3,4 and by second option we get @=0,9 then by combining two options we get @=0 ?

On the GMAT, two data sufficiency statements always provide TRUE information and these statements NEVER contradict each other or the stem.

From (1) @ could be 0, 1, 2, 3, or 4.
From (2) @ could be 0 or 9.

Both to be true {@} has to be 0.
