CA = chronological age = 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "80 = 100(MA/12) --> MA = 9.6 (lower bound)
\n" ); document.write( "140 = 100(MA/12) --> MA = 16.8 (upper bound)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "9.6 < MA < 16.8
