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.

Chose (C) but i'm afraid I might be wrong since I've read many of you chose (B)
My reasoning? 3,x, and y are consecutive odd integers in ascending order. 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?

The correct answer is B.

We are told that 3, x, and y are consecutive odd integers in ascending order.

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.

# 1:
x,y : can be any no so in sufficient

#2:
3,x,y are consective odd integers in ascending order so x,5,y 7

sufficient

IMO B
