1) 1 fifty pence piece and 1 nickel. It's right because one is not a nickel but the other one is.
2) 5 + 7 = 12
3) Same distance

1. It takes a man an hour to dig a hole. How long does it take two men to dig half a hole?
2. A water lily growing in a circular pond doubles in size every day. It takes thirty days to cover the whole pond. How long does it take to cover half the pond?
3. A builder builds 100 houses. He has to number them all so he goes to the hardware store. How many no. 9's does he buy?
4. A man is travelling from the country to Dublin. He comes to a T-Junction. There are no signposts. He spots a house down the road and decides he will go and ask whoever lives there the way to go. Just before he enters the garden, a little boy comes up and tells him that there are twins living in the house on their own. He says that one of them always tells the truth and one of them always lies and that no one can tell which is which. He also says that anyone who wants information can only ask them one question and that is it.
Bearing in mind that he won't know which twin answers the door.. what question does he ask, and then, what action does he take to make sure he goes the right way?
5. Spot the error in this? There was a taxi outside a hotel. A man came out, hit the taxi driver on the head, took all the money out of the meter and started to run off, only to be rugby-tackled by the commissionaire?
6. A farmer has to transport a fox, a goose and a sack of grain across a river. The boat is so small that there is room only for him and one of the others at a time, but if he leaves the fox and goose together the fox will kill the goose, and if the goose and the sack of grain are left together the goose will eat the grain. How does he get them all over?

First, move your right foot as if you were making a clockwise circle with it (as if you had to paint a circle in the sand with it)
Easy? right. Now try to write an imaginary 6 with your right hand at the same time, 98% can't do it simultaneously!

AND A LIGHT BULB
>=P 100 prisoners are imprisoned in solitary cells. Each cell is windowless and soundproof. There's a central living room with one light bulb; the bulb is initially off. No prisoner can see the light bulb from his or her own cell. Each day, the warden picks a prisoner equally at random, and that prisoner visits the central living room; at the end of the day the prisoner is returned to his cell. While in the living room, the prisoner can toggle the bulb if he or she wishes. Also, the prisoner has the option of asserting the claim that all 100 prisoners have been to the living room. If this assertion is false (that is, some prisoners still haven't been to the living room), all 100 prisoners will be shot for their stupidity. However, if it is indeed true, all prisoners are set free and inducted into MENSA, since the world can always use more smart people. Thus, the assertion should only be made if the prisoner is 100% certain of its validity.
Before this whole procedure begins, the prisoners are allowed to get together in the courtyard to discuss a plan. What is the optimal plan they can agree on, so that eventually, someone will make a correct assertion?
