\r\n" );
document.write( "For a moment, put away four nickels from the collection.\r\n" );
document.write( "\r\n" );
document.write( "Then you have equal number of nickels and dimes, and you can group them in pairs, each containing one nickel and one dime.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then each pair is worth 5 + 10 = 15 cents, while the entire reduced collection is worth  125 - 4*5 = 105 cents.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the number of such pairs is   = 7.\r\n" );
document.write( "\r\n" );
document.write( "Thus, you have 7 dimes in the original collection, and 7 + 4 = 11 nickels.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  11 nickels and 7 dimes:  11*5 + 7*10 = 55 + 70 = 125 cents in all.  ! Correct !\r\n" );
