Puzzle 37 


I started out on the journey from the forest with a full tank of fuel, 12 gallons exactly.

However, the moment I started out, the fuel tank sprung a leak. I travelled at 50 mph until I ran out of fuel exactly 4 hours later.

I know that the car does 25 miles for each gallon.

How much fuel had I lost through the hole?

Puzzle 38 


Recently Kevin had a party and because it was his birthday he wanted a mathematical cake!

He ordered a cake in the shape of a cube and had it completely iced (but of course they didn't ice the underneath because that just isn't very sensible).

He cut every side of the cake into three equal pieces, giving 27 slices of cake.

He ended up eating all of the pieces of cake that had exactly 2 sides with icing.

So, how many pieces did that leave for the guests?
