A couple of puzzles - the fist one is for warming up and the second one needs some creative thinking! Now that we are warmed up, here is a harder one!Back in the old days ships of yesteryear were driven by steam and it was often the case that the ship would outlive the engine and the boiler and they'd have to replace them.
"Now, take one ship for example. When you add the age of the ship and the age of its boiler, it totals 42 years. The ship is twice as old as the boiler was when the ship was as old as the boiler is now."
The question is how old are they?
Pandora, Harry, Alec, Gemima and Geoffrey are animals in a zoo. The other day one of them ate an animal called Tabitha. Who ate her and what type of animal was it?

Answers: Puzzle 1
S + B = 42 --(1)
Ship was as old as the boiler
(S-B) years ago. At that time, the boiler was B - (S-B) years old. That is, 2B - S years old. Now, the ship is twice as old as boiler was at that time.
S = 2*(2B - S) or 3S = 4B --(2)
From (1) and (2), S = 24, B=18

Puzzle 2: Alec ate Tabitha (Alec ate her = alligator!)
