Let the age of Janet be x.
\n" ); document.write( "Given,George is 3 years older than his sister Janet.
\n" ); document.write( "So the age of George = x+3
\n" ); document.write( "After seven years, their ages will be x+7 and (x+3)+7
\n" ); document.write( "Given, (x+7)/(x+10) = 6/7
\n" ); document.write( " 7(x+7) = 6(x+10)
\n" ); document.write( " 7x+49 = 6x+60
\n" ); document.write( " 7x-6x = 60-49
\n" ); document.write( " x = 11
\n" ); document.write( "Therefore, the age of Janet is 11 years
\n" ); document.write( "
\n" ); document.write( "
