At a Halloween party, 2/5 of the people were dressed as vampires, 1/3 were dressed as ghosts; everyone else at the party, were equally dressed as Pirates, Robin Hood, Fairies, and Princesses. If all of the Fairies leave the party, and the people who just arrived to the party are all dressed as ghosts, doubling the number of ghosts at the party, what proportion of the people at the party are vampires? Choose the correct choice from the following answers
A) 6/19
B) 5/18
C) 5/26
D) 1/2
E) 3/7
Vampires = 2/5 = 6/15   Ghosts = 1/3 = 5/15   Pirates + Robin Hoods + Fairies + Princesses = 1 - (5/15 + 6/15) = 4/15, so each = 1/15   If Ghosts doubled (2)(5) = 10, and now Fairies = 0; then, total = 6 + 10 + 1 + 1 + 1 + 0=
