let x,y,z be the ages of harry,ron and hermoine respectively.
\n" ); document.write( "Harry is 1/3 as old as Ron
\n" ); document.write( "=>x=y/3--------------(1)
\n" ); document.write( "z-x=8----------------(2)
\n" ); document.write( "Harry is 8 years old
\n" ); document.write( "so, from (1) 8=y/3 =>y=24 yrs
\n" ); document.write( "again from (2)z=8+x=8+8=16=>z=16yrs
\n" ); document.write( "The sum of their ages = 8+16+24=48 yrs\r
\n" ); document.write( "\n" ); document.write( "
