x = original price per liter
\n" ); document.write( "(0.92)x = reduced price per liter
\n" ); document.write( "y = liters purchased at price x for 420 rupee
\n" ); document.write( "---
\n" ); document.write( "xy = 420
\n" ); document.write( "(0.92)x(y + 2) = 420
\n" ); document.write( "(0.92)xy + (0.92)2x = 420
\n" ); document.write( "(0.92)420 + (0.92)2x = 420
\n" ); document.write( "386.4 + (1.84)x = 420
\n" ); document.write( "(1.84)x = 420 - 386.4
\n" ); document.write( "x = (420 - 386.4)/1.84
\n" ); document.write( "x = 18.261
\n" ); document.write( "reduced price per liter = (0.92)18.261
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "reduced price per liter = 16.80 rupee/liter
