If the least common multiple of two prime numbers x and y is 10, where x > y, then the value of 2x + y is	Choose the correct choice from the following answers:  A) 7  B) 9  C) 11  D) 12  E) 21
LCM of two prime numbers will basically be multiple of those numbers. LCM = 10 = 2*5, both of which are prime.   Now we know x&gt;y, so x=5 and y =2.   2x+y = 2*5 + 2 = 10 + 2=
