25 litres of salt solution contain 6% salt. How many litres of water must be added so as to get a resultant solution containing 5% salt.
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "water + water = water
\n" ); document.write( "0.94*25 + x = 0.95(25+x)
\n" ); document.write( "-------
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "94*25 + 100x = 95*25+95x
\n" ); document.write( "5x = 25
\n" ); document.write( "x = 5 liters (amt. of water needed)
