Answer to the Friday Puzzle….

Answer to the Friday Puzzle…..

On Friday I posted this puzzle….

Given a sack of sugar, an unbalanced scale, and two 5-pound weights, measure exactly 10 pounds of sugar.

If you have not tried to solve it, have a go now.  For everyone else the answer is after the break.

Put both of the weights in one pan and pour the sugar into the other pan until the scales balance. Then remove the weights and pour sugar into the first pan until it balances again. The first pan will contain exactly 10 pounds of sugar.

Any other solutions?
