Best Friends Tim, Bob and Dave. Each contribute £5 a total of £15 therefore each share is 5

They purchase a TV for £15

After they all leave the shop. The shop keeper tells his cashier there has been a mistake and the cost was only £10. Take these £5 coins and give it to Tim, Bob and Dave.

The cashier keeps 2 and hands back £1 to Tim, £1 to Bob, and £1 to Dave.

Tim has now paid a total of £4, as so Bob and Dave.

If 3 x 4 = 12 and the cashier has £2. 12+2 = 14

Where is the other £1?
