The answer to last week’s question is. There is a barrel with no lid and some beer in it. “This barrel is more than half full,” said Chuck. “No it’s not,” say Phil. “It’s less than half full.” Without any measuring implements and without removing any beer from the barrel, how can they easily determine who is correct?

A: They must tilt the barrel until the beer reaches the rim of the barrel. If they can see the bottom of the barrel then it is less than half full.

This week’s lateral challenge is.

Q: Farmer Smith has 3 pink pigs, 4 brown pigs and 1 black pig. How many of the pigs can say that it is the same colour as another pig on Smith’s farm?

The answer along with a new challenge, next year.





Stay safe & have a great New Years Eve!

    What an elegant answer for barrel problem! To just tilt the barrel until the beer reaches the rim of the barrel; So simple and definite!
