Puzzle 51 



Many years ago, a cruise liner sank in the middle of the ocean.

The castaways luckily landed on a remote desert island.

There was enough food for the 220 people to last three weeks.

Six days later a rescue ship appeared, unluckily this ship also sank, leaving an additional 55 people stranded on the island to now share the original rationed food.

The food obviously had to be re-rationed, but everyone was now on one-half of the original ration, so how many days in total would the food last for, from the day of the original sinking?

A local angler caught a large trawler load of haddock.

They decided to donate some of the fish to the local community, 1,672 people in all.

Every person over 50 received 16 fish, and to every person under 50 received 96 fish.

Only 3/4 of the over 50s collected their haddock, and only 1/8 of the under 50s collected their fish.

How many fish did the angler give away?
