MindTwisters


Psyche Them

 

Impress your friends with your psychic abilities. Give a friend a dime and a nickel. Tell him (or her) to hold one coin in his right hand and the other one in his left hand.
Ask him to triple the value of the coin in his right hand and double the value of the coin in his left hand. Add these two values. If the sum is even number, the dime is in his right hand, if the sum is odd, the dime is in his left hand.

While your friends may well believe that you do have psychic powers, Dositey MindTwister problem solvers know there is a simple explanation. Explain how this method works.
