\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "Thirty-three kilograms of nickel that was 35% pire were mixed with a nickel alloy that was 21% pure. How many kilograms of each kind were used to produce an alloy that was 27% pure?
\n" ); document.write( "LET 21% NICKEL USED = X KG
\n" ); document.write( "WE GET X+33 KG OF 27% NICKEL ALLOY
\n" ); document.write( "NICKEL IN 35% PURE ALLOY = 33*35/100
\n" ); document.write( "NICKEL IN 21% NICKEL ALLOY = X*21/100
\n" ); document.write( "NICKEL IN 27% NICKEL ALLOY = (X+30)*27/100
\n" ); document.write( "SO.....
\n" ); document.write( "33*35/100 + X*21/100 = (X+30)*27/100
\n" ); document.write( "1155+21X=27X+810
\n" ); document.write( "27X-21X=1155-810=345
\n" ); document.write( "6X=345
\n" ); document.write( "X=57.5 KG\r
