Re: Maths problems (interesting ones)

Right,

For the coins one you can't do it unless you know whether its heavier or lighter.
if you know whether it is heavier or lighter:
put 6 on either side of the scales and weigh
One side will be lighter than the other so you take the side witth the heaveier or lighter one and weigh 3 on 3. One side will be heavier/lighter. Then weigh 1 on 1 of and leave one off. If it is even then the 3rd is fake. If it is not even then the heavier/lighter side is fake
