Most people will think it's 42, but remember, the first person shakes the hand of 6 people. The SECOND person shakes the hand of 5 people, and on and on until the sixth person only shakes one hand. Use this to figure out the answer!
Jack had only $2, but he needed $3 for his cab fare home. He went to a pawn shop and pawned his $2 for $1.50. Jack then bumped into Don and told him that he would sell him his $2 pawn ticket for $1.50. Dan agreed. Since Jack started out with $2, and he ended up with $3, who is out the extra dollar and why?
