A local fisherman caught a large trawler load of haddock.
He decided to donate some of his fish to the local community, 1,672 people in all.
To each person over 50 he gave 16 fish and to each person under 50 he gave 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 fisherman distribute it total?
Answer: 20,064 fish.
As only 3/4 of the over 50s claimed 16 fish, this averages out to 12 fish each.
Similarly only 1/8 of the under 50s claimed 96 fish, this again averages out to be 12 fish each.
Therefore the total number of fish was 1,672 x 12 = 20,064.
It doesn't matter how many over/under 50s there are.
