\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " Solution.
\n" ); document.write( "Let the sister's age be x yrs
\n" ); document.write( "then,
\n" ); document.write( "from your first sentence,
\n" ); document.write( "Martin's age =(x+5) yrs
\n" ); document.write( "From your second sentence,
\n" ); document.write( "Five years ago,
\n" ); document.write( "sister's age=x-5
\n" ); document.write( "then,
\n" ); document.write( "martin's age=(x+5)-5=x
\n" ); document.write( "but,martin was two times older,
\n" ); document.write( "therefore,
\n" ); document.write( "x=2(x-5)
\n" ); document.write( "solving the resulting equation,
\n" ); document.write( "x=2x-10
\n" ); document.write( "2x-x=10
\n" ); document.write( "x=10
\n" ); document.write( "sister's age is 10yrs,
\n" ); document.write( "martin's age=x+5
\n" ); document.write( " =10+5=15yrs \n" ); document.write( "
\n" );
