1.How many liters of 22% salt solution must be added to 75 liters of 67% salt to get a 47% salt solution?
\n" ); document.write( ":
\n" ); document.write( "Let x = no. of liters of 22% solution:
\n" ); document.write( ":
\n" ); document.write( "Resulting amt = (x+75)
\n" ); document.write( ":
\n" ); document.write( ".22x + .67(75) = .47(x+75)
\n" ); document.write( ".22x + 50.25 = .47x + 35.25
\n" ); document.write( ".22x - .47x = 35.25 - 50.25
\n" ); document.write( "-.25x = -15
\n" ); document.write( "x = -15/-.25
\n" ); document.write( "x = +60 liters of 22% solution:
\n" ); document.write( ":
\n" ); document.write( "Check:
\n" ); document.write( ".22(60) + .67(75) = .47(60+75)
\n" ); document.write( " 13.2 + 50.25 = .47(135)
\n" ); document.write( ":
