\r\n" );
document.write( "Take off these 12 nickels (mentally).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then you will have equal number of nickels and dimes and the updated total value of coins is $5.10 - $0.05*12 = $4.50.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now you can group the remaining coins in pairs containing 1 nickel in 1 dime in each pair.\r\n" );
document.write( "Each pair worth is 5 + 10 = 15 cents.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "How many pairs do you have now ? -  = 30.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, initially there were 30 dimes and 30 + 12 = 42 nickels.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  30 dimes and 42 nickels.\r\n" );
