Let Q represent a set of six distinct prime numbers. If the sum of the numbers in Q is even and x is a member of Q, then what is the least possible value that x can be?
Choose one
A) 1  B) 2  C) 5  D) 3  E) 7
Q = p1+p2+p3+p4+p5+p6 = even (and all primes are distinct)   if the least prime is 2 then we have sum of Q = odd....hence 2 is not possible1 is not prime.   next least prime is 3, this satisfies the given condition that sum of Q = even.   Ans. D. 3
