\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "To solve the problem mentally, take off one 5-peso coin apart, for a minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "You will have a collection of 180 pesos total, consisting of equal amount of 5-peso coins and 10-peso coins.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Group these coins in sets containing one 5-peso coin and one 10-peso coin.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Each set is worth 5+10 = 15 pesos, and the number of such groups is  \"180%2F15\" = 12.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, there were 12 10-peso coins and 13 5-peso coins in the original collection.    ANSWER\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  12*10 + 13*5 = 120 + 65 = 185 pesos, in total.    ! Correct !\r\n" );
