\n" ); document.write( " $\"C%5B1%5D\"$ =30% orange
\n" ); document.write( " $\"C%5B2%5D\"$ =5% orange
\n" ); document.write( "To get 25L, $\"C%5B1%5D%2BC%5B2%5D=25L\"$ ----------------------------> eqn 1
\n" ); document.write( "In eqn 1 we get,
\n" ); document.write( " $\"C%5B2%5D=25-C%5B1%5D\"$ -----------------------------------------> eqn 2
\n" ); document.write( "Also,
\n" ); document.write( " $\"0.30C%5B1%5D%2B0.05C%5B2%5D=25%280.10%29\"$ ---------------------------> eqn 3
\n" ); document.write( "Subst. eqn 2 in eqn 3,
\n" ); document.write( " $\"0.30C%5B1%5D%2B0.05%2825-C%5B1%5D%29=2.50\"$
\n" ); document.write( " $\"0.30C%5B1%5D%2B1.25-0.05C%5B1%5D=2.50\"$
\n" ); document.write( " $\"0.25C%5B1%5D=2.50-1.25=1.25\"$
\n" ); document.write( " $\"cross%280.25%29C%5B1%5D%2Fcross%280.25%29=cross%281.25%295L%2Fcross%280.25%29\"$
\n" ); document.write( " $\"highlight%28C%5B1%5D=5L%29\"$ , 30% orange juice
\n" ); document.write( "And, via eqn 2: $\"highlight%28C%5B2%5D=25-5=20L%29\"$ , 5% orange juice
\n" ); document.write( "In doubt? Go back eqn3 ,
\n" ); document.write( " $\"0.30%2A5%2B0.05%2A20=25%2A0.10\"$
\n" ); document.write( " $\"1.50%2B1=2.50\"$
