document.write( "A man is twice as old as his son. His son is twice as old as his sister. Their total ages is 84. How old is the father\r\n" );
document.write( "\r\n" );
document.write( "Let the daughter's age be \"x\"\r\n" );
document.write( "Then the son's age is \"2%2Ax\" and the father's age is \"2%2A2%2Ax+=+4%2Ax\"\r\n" );
document.write( "Sum of ages is 84. i.e. \"x+%2B+2%2Ax+%2B+4%2Ax+=+7%2Ax+=+84\"\r\n" );
document.write( "Therefore, \"x+=+84%2F7+=+12\"\r\n" );
document.write( "Daughter's age = \"highlight%2812%29\"\r\n" );
document.write( "Son's age = \"highlight%2824%29\"\r\n" );
document.write( "Father's age = \"highlight%2848%29\"\r\n" );
