Solution A
\n" ); document.write( "Amount = x liters
\n" ); document.write( "Concentration =40% = 0.40
\n" ); document.write( "=======================================================
\n" ); document.write( "Solution B
\n" ); document.write( "Amount =(106- x) liters
\n" ); document.write( "Concentration =25% = 0.25
\n" ); document.write( "=======================================================
\n" ); document.write( "Resultant Solution
\n" ); document.write( "Amount = 106 liters
\n" ); document.write( "Concentration = 36%=0.36
\n" ); document.write( "=======================================================
\n" ); document.write( "[Amount Solution A * Concentration A] + [Amount Solution B * Concentration of B] = Amount of Resultant * Concentration of resultant
\n" ); document.write( "========================================================
\n" ); document.write( "Put the value in above equation
\n" ); document.write( "(x*0.40)+((106-x)*0.25=106*0.36
\n" ); document.write( "0.40x+26.5-0.25x=38.16
\n" ); document.write( "0.15x=38.16-26.5
\n" ); document.write( "0.15x=11.66
\n" ); document.write( "Divide by 0.15 both sides
\n" ); document.write( "0.15x/0.15=11.66/0.15
\n" ); document.write( "x=77.73
\n" ); document.write( "=======================================
\n" ); document.write( "Amount of solution A = 77.73 liters
\n" ); document.write( "Amount of Sultion B = 106-77.73=28.27 liters
\n" ); document.write( "
\n" ); document.write( "
\n" );
