What two coins equal 30 cents but one is not a nickel?
Could you elaborate on the puzzle: "What two coins equal 30 cents but one is not a nickel?" This seems like an intriguing riddle, especially considering the standard denominations of U.S. coins. Are we to assume that we're dealing with only coins that are currently in circulation? If so, how could we possibly arrive at 30 cents without using a nickel, which is worth 5 cents? Is there a unique combination of coins that would satisfy this condition, or are there multiple possibilities? I'm curious to know the answer and the reasoning behind it.
