(
Money Puzzles)
What is the largest sum of money--all in current silver coins and no
four-shilling piece--that I could have in my pocket without being able
to give change for a half-sovereign?
Answer:
The largest possible sum is 15s. 9d., composed of a crown and a
half-crown (or three half-crowns), four florins, and a threepenny piece.
