\n" ); document.write( "Comment:: Since the difference is only 10 the 2 numbers are
\n" ); document.write( "close to each other----
\n" ); document.write( "1st guess:: 60 and 70
\n" ); document.write( "Checking:: 60+70 = 130 ; 70-60 = 10*
\n" ); document.write( "lesser = y = 60
\n" ); document.write( "other = x = 70
