Riddle 1: It is greater than God and more evil than the devil. The poor have it, the rich need it and if you eat it you’ll die. What is it?
Riddle 2: How many pairs of animals did Moses have on the ark?
Riddle 3: You have 9 balls, equally big, equally heavy – except for one, which is a little heavier.
How would you identify the heavier ball if you could use a pair of balance scales only twice?
Answer to riddle 1: Nothing. Nothing is greater than God, nothing is more evil than the devil, the poor have nothing, the rich need nothing and if you eat nothing you’ll die.
Answer to riddle 2: Trick question! Noah was the one with the animals on the ark along with his family.
Answer to riddle 3: Divide the 9 balls into 3 groups of 3. Compare the weight of two of those groups.
The heavier group should then be obvious, it will either tip the scales, or, if the scales stay balanced, then it is the group you didn’t include.
Now, choose 2 balls from this group and compare their weights, and using the same logic as before, the heavier ball will be obvious.
