A

you atleast have one integer divisible by 3 for every 3 consecutive numbers, the question says 4 consecutive numbers thus A

Stmt-2 does not provide any info thus insufficient

For Statement 1, why couldn't the 4 integers by 0, 1, 2, 3? In which case, r=0.

Hi metskj127,

You are right about the possibility of 4 integers being 0,1,2,3, in which case r = 0. The question statement asks us about r being divisible by 3 i.e. is the remainder 0 when r is divided by 3. If you divide 0 by 3, the remainder is 0.

Thus, even if r = 0, we can say that r is divisible by 3.

The takeaway from this can be " Zero is divisible by any integer i.e. every integer is a divisor of Zero" as zero divided by anything gives the remainder as zero.

Hope its clear!

Regards
Harsh

Hi metskj127,

The GMAT will sometimes test you on concepts that you know, but in ways that you're not used to thinking about (as is the case here).

This specific concept can appear in other ways. When most people think of "multiples", they only think of POSITIVE multiples.

eg. Multiples of 10: 10, 20, 30, 40, etc.

But 10x0 is ALSO a multiple of 10, so the above list should INCLUDE the number 0. Don't be surprised if this exact issue shows up in one of your DS questions on Test Day...

GMAT assassins aren't born, they're made,
Rich
