HOW MUCH SALT MUST BE ADDED TO 60 KG OF A 20% SOLUTION OF SALT TO INCREASEE IT TO A 40% SOLUTION OF SALD
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "salt + salt = salt
\n" ); document.write( "0.20*60 + 1*x = 0.40(60+x)
\n" ); document.write( "-----
\n" ); document.write( "20*60 + 100x = 40*60 + 40x
\n" ); document.write( "60x = 20*60
\n" ); document.write( "x = 20 KG (amt of salt that must be added)
