\n" ); document.write( "Total calculators=46
\n" ); document.write( "So, $\"SC%2BGC=46\"$ -------------------------> eqn 1
\n" ); document.write( "In eqn 1 we get,
\n" ); document.write( " $\"SC=46-GC\"$ ----------------------------> eqn 2
\n" ); document.write( "Also,
\n" ); document.write( " $\"11SC%2B54GC=1667\"$ ----------------------> eqn 3
\n" ); document.write( "Subst. eqn 2 in eqn 3,
\n" ); document.write( " $\"11%2846-GC%29%2B54GC=1667\"$
\n" ); document.write( " $\"506-11GC%2B54GC=1667\"$
\n" ); document.write( " $\"43GC=1667-506=1161\"$
\n" ); document.write( " $\"cross%2843%29GC%2Fcross%2843%29=cross%281161%2927%2Fcross%2843%29\"$
\n" ); document.write( " $\"GC=27pcs\"$ , Number of Graphic calc.
\n" ); document.write( "Via eqn 2:
\n" ); document.write( " $\"SC=54-27=19pcs\"$ , Number of Scientific calc.
\n" ); document.write( "Check via eqn 3:
\n" ); document.write( " $\"11%2819pcs%29%2B54%2827pcs%29=1667\"$
\n" ); document.write( " $\"209%2B1458=1667\"$
\n" ); document.write( " $\"1667=1667\"$
