 Rado Nov 01, 2001 What about 45 pennies, 2 nickels, 2 dimes and a quarter? dewtell Jul 31, 2002 That also works. In general, you can substitute a quarter and 23 pennies (24 coins, 48 cents) for 6 nickels and 18 pennies (also 24 coins and 48 cents), but you can only do that once to the initial solution. The key to this problem is to recognize that the average value has to be 2 cents per coin, so you need to group enough pennies with each larger coin to keep the average of each group at 2 cents per coin. beetee Aug 01, 2003 THE US MINTED A 2CENT PIECE FOR SOME YEARS 1800'S canu Jul 13, 2004 Information on US 2-cent coins: www.coinfacts.com/two_cents/two_cents_by_date.html Question_Mark Oct 27, 2005 If this was the UK, it would be: 40 1p's, 2 10p's, 8 5p's (£1). Question_Mark Nov 02, 2005 Wait! Here is the UK's more sensible option. 50 2p's . SPUTNIK2 Feb 06, 2006 good one! Atropus Feb 12, 2006 2p coins sound like the way to go ^_^ My country (New Zealand) got rid of 2c coins in 1989-1990. We are about to lose 5c coins also. Then again, most transactions here are electronic. gorillazgirl Jul 03, 2006 that was fun!! rrn0rrnrrnY Sep 08, 2006 I agree with Rado, but don't mind that there isn't just one answer. I enjoyed thinking it out without it giving me a headache. Thanks for a good teaser!
