\r\n" );
document.write( "Take aside 5 extra dimes for a minute from the collection (do it MENTALLY).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the collection will worth $54.05 - 5*$0.1 = $53.55.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "But now there are equal number of nickels and dimes in the collection,\r\n" );
document.write( "so you can group coins in the sets, containing one nickel and one dime each.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus each set of the two coins is worth 5 + 10 cents; hence the number of these sets is   = 357.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now return back those 5 extra dimes to get the \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  There were 357 nickels and 357+5 = 362 dimes in the original collection.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.   5*357 + 10*362 = 5405 cents = $54.05.    ! Corrct !\r\n" );
