cp of 11 pens = x
cp of 1 pen = x/11
sp of 10 pens = x
sp of 1 pen = x/10
x/10 > x/11
therefore its a gain
gain = x/10 - x/11
= (11x - 10x )/110
= x/110
% = (x/110)/(x/11) x 100
= 10%
cp of 1 pen = x/11
sp of 10 pens = x
sp of 1 pen = x/10
x/10 > x/11
therefore its a gain
gain = x/10 - x/11
= (11x - 10x )/110
= x/110
% = (x/110)/(x/11) x 100
= 10%
