1) x and y could be any of the primes. Insuff.
2) 3, 5, 7... odd consec integers in ascending order. Since they are consecutive we cant have 3, 9, 11, etc...
must be 3, 5, 7. 5+7=12. Suff.
Am i missing somethin really basic?
owell i say B.

ok, it is B,
1) INSUFF
2) SUFF
3,5,7> consequtive odd intengers
sorry for so many corrections...

in 2 can 3, 7 and 9 be a consecutive odd integers in ascending order?

Why can't we have 1, 1 and 3 instead of 3,5 and 7.

Because the question says:
3, x, and y are consecutive odd integers in ascending order

Question doesn't say 3<x<y, so it can be 1, 1 and 3 as well as 3, 5 and 7
Anyway, OA is B.

No, but you have a point there..
1,1,3> ascending consecutive odd intengers
3,5,7> ascending consecutive odd intengers
the asnwer should be C
any comments?? plzz

Haha, should do this more often. Throw a few easy ones in there to confuse the hell out of us .

yes, but it is very confusing when there is no written rule for why we should accept one alternative over another.
In this case, what makes 3,5,7 better possibility than 1,1,3 ?
1,1,3> ascending consecutive odd intengers
3,5,7> ascending consecutive odd intengers
I wonder if 2nd statement is written correctly, i mean if said
'numbers in S are in ascending order and .....', B would make sense

When they say in ascending order do they mean literally in the same order as they state them (3,x, and y) or just in ascending order but could be x,3,y or 3,x,y etc...? For me it isn't clear but what do you guys think?

My guess is left to right shows ascending or descending order 3, 5, 7 here ascending 3, 1, 1 here descending so when it says 3, y and z are consecutive odd integers in ascending order then y and z must be 5 and 7 because if it was 3, 1 and 1 then it would become descending.

(2) 3, x, and y are consecutive odd integers in ascending order statement 1: no specific value of x and y. Not sufficient . Statement 2: ascending order . consecutive odd. x= 5 y=7. x + y = 5 + 7 = 12. B is the correct answer.

I think C?
Statement 1 = prime numbers = insufficient.
Statement 2 = The way I read the problem is 3, x, and Y are consecutive Odd integers in ascending order. Which means that the set can be
1, 3, 5 or 3, 5 7. If this is the case then statement 2 is insufficient.
If we take both statements combined, then 3, 5, 7 are the only consecutive odd integers in ascending order and still prime.

(2) 3, x, and y are consecutive odd integers in ascending order Statement 1: x and y are prime numbers Possibility 1: S = {2,3,2,3} > Sum = 2+3 = 5 .....(since we are not told whether the set has distinct integers or different ones) Possibility 2: S = {2,3,5,7} > Sum = 5+7 = 12 More than 1 possibility. Insufficient. Statement 2: 3, x, and y are consecutive odd integers in ascending order. Possibility 1: S = {2, 3, 5, 7} > Sum = 5+7 = 12 There can be only 1 possibility of "consecutive odd integers in ascending order". Sufficient. Hence, option B.
