\n" ); document.write( "==============
\n" ); document.write( "Method 1:
\n" ); document.write( "Add W grams.
\n" ); document.write( "100*30 + W*0 = (100+W)*10
\n" ); document.write( "10W + 1000 = 3000
\n" ); document.write( "W = 200 grams
\n" ); document.write( "----------------
\n" ); document.write( "Method 2:
\n" ); document.write( "100 gms of 30% = 30 grams of acid
\n" ); document.write( "For 30 to be 10%, the total is 300 grams.
