hari is twice as old as his son. twenty years ago, he was four times as old as the son.find the present age of each
\n" ); document.write( "Solution:Let the age of hari = h
\n" ); document.write( "and the age of son = s
\n" ); document.write( "hari is twice as old as his son------>h = 2s
\n" ); document.write( "twenty years ago...
\n" ); document.write( "h-20 = 4(s-20)(plug in h = 2s from the equation above )
\n" ); document.write( "2s-20 = 4(s-20)
\n" ); document.write( "2s-20 = 4s-80
\n" ); document.write( "4s-2s= 80-20
\n" ); document.write( "2s= 60
\n" ); document.write( "s= 60/2 = 30
\n" ); document.write( "so son's present age is 30 years
\n" ); document.write( "and hari's present age is 2* 30 = 60 years \n" ); document.write( "

\n" );
