RE "So £27 + £2 = £29."
isnt right
should read "£27 - £2 = £25"
£25 - being the correct price of the TV
£2 - being what the assistant pocketed
£27- being what the three ladies paid in total ( £9 a piece)
The island of Elbonia have a rather eccentric postal system. Postage for an item can be anything from 1 dinar to 15 dinari, and you must use exact postage. Frustratingly, there is only space on the envelopes in Elbonia to attach a maximum of three stamps. What is more, they only have three different denominations of stamps, can you work out what they are?
