document.write( "To solve this problem, group (MENTALLY) all the coins in sets containing 4 nickel and one dime each.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Each set (group) of coins then is worth  4*5+10 = 30 cents.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the number of such groups is   = 13.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
