document.write( "\r\n" );
document.write( "Ans:\r\n" );
document.write( "Let B's age be x\r\n" );
document.write( "A's age = 4*x\r\n" );
document.write( "C's age = x - 9\r\n" );
document.write( "Sum = \"4%2Ax+%2B+x+%2B+x+-+9+=+63\"\r\n" );
document.write( "i.e. \"6%2Ax+=+72\" or \"x+=+12\"\r\n" );
document.write( "\r\n" );
document.write( "So B's age = \"highlight%2812%29\"\r\n" );
document.write( "A's age = \"4%2A12\" = \"highlight%2848%29\"\r\n" );
document.write( "C's age = \"12+-+9\" = \"highlight%283%29\"\r\n" );
