Let the boy's age be x years now.
\n" ); document.write( "So 5 yrs ago his age was (x-5) yrs.
\n" ); document.write( "According to the problem,
\n" ); document.write( "present age = 2*(age 5 yrs ago)
\n" ); document.write( "x = 2*(x-5)
\n" ); document.write( "x = 2x - 10
\n" ); document.write( "x = 10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The boy is now 10 yrs. old.
