Oops, I meant that true that 49 (sum=13) is divisible by 7 but 58(sum=13) is not divisible by 7

#1 - Insufficient; the only number that works is 49 but none of the others do.

#2 - Insufficient; only numbers valid are: 35, 63, 91 and 98 - but there are many more not divisible by 7

#3 - Insufficient; '4' in 49 is not divisible by three

Remember, this is a yes or no question. If is not possible for the statements to give you a definitive answer, then the statement is insufficient.

mihir14, I believe your reasoning is wrong. Agree that each statement by itself is insufficient but both statements together can bring you to the conclusion that the answer is not a multiple of 7. Your exemple that 49 is not divisible by 3 is not appropriate because, precisely, 49 is not even divisible by 3 in the first place so it could not serve as exemple. The numbers whereby R+M = 13 are 49-94-58-85-67-76 and none of those are divisible by 3. Therefore, nevermind a multiple of 7, no number can satisfy those requirements and C conveys that
