-------------- percent ---------------- Amount
\n" ); document.write( "Sugar solution 40 ---------------- 200 ml
\n" ); document.write( "water 0 ---------------- x ml
\n" ); document.write( "Total 10 ---------------- 200 + x ml
\n" ); document.write( "
\n" ); document.write( "40 * 200 + 0 x = 10 ( 200 + x )
\n" ); document.write( "8000 + 0 x = 2000 + 10 x
\n" ); document.write( "0 x -10 x = -8000 + 2000
\n" ); document.write( "-10 x = -6000
\n" ); document.write( "/ -10
\n" ); document.write( "x = 600 ml water
