Question 163313
</pre><font size=4><b>
Total calculators=46
So,{{{SC+GC=46}}} -------------------------> eqn 1
In eqn 1 we get,
{{{SC=46-GC}}} ----------------------------> eqn 2
Also,
{{{11SC+54GC=1667}}} ----------------------> eqn 3
Subst. eqn 2 in eqn 3,
{{{11(46-GC)+54GC=1667}}}
{{{506-11GC+54GC=1667}}}
{{{43GC=1667-506=1161}}}
{{{cross(43)GC/cross(43)=cross(1161)27/cross(43)}}}
{{{GC=27pcs}}}, Number of Graphic calc.
Via eqn 2:
{{{SC=54-27=19pcs}}}, Number of Scientific calc.
Check via eqn 3:
{{{11(19pcs)+54(27pcs)=1667}}}
{{{209+1458=1667}}}
{{{1667=1667}}}
Thank you,
