After reading the magical electronic manuscript presented in
The king of Swahili realises his riddle was too easy. Very few get beheaded and his treasure of gold is getting smaller by the day. So he increases the difficulty and presents every contestant with 25 bags of coins. Not before long however people come up with a solution ... Could You?
The king then decides not to accept any contestants for a week, during which he will decide how he can make the riddle more difficult. For several days he ponders on this and decides to limit the number of times they can use the royal scales to 4. Next he starts wondering, 'How many bags of coins shall I present them with?'
Although he rather beheads somebody then to give them gold, the king is an honest man and wants to be sure the riddle can be solved. Unfortunately he was told the original riddle and was never able to solve it himself so how could he solve it if were more difficult? For days and nights he thinks about nothing else till suddenly the solution comes to him.
The next morning the royal gards hang out the new riddle which now reads:
'Given you can only use the royal scales 4 times and you have to hand 4 bags of coins back to the king every time you use them, what would be the maximum number of bags from which the counterfeits could be isolated?'
Whoever comes out with the most coins will get the points.
