Profit = SP - CP = 110 - 95 = 15
Profit % = ( 15 / 95 ) * 100 = 15.8%

price of 10 pens (CP)=95
total pen to be sell =10+1(extra)=11
total SP=11*10=110
gain=110-95=15
% gain=gain*100/CP=15*100/95=15.8

Each set contains additional pen so 11 pens are bought at Rs. 95

1 pen sold at Rs. 10 so 11 will be sold at 110

So profit on 11 pens= Rs. 15

So profit %= 15*100/95= 15.8

Madhusudhan Vaddi   9 years AGO

1 set of 10 pens + 1 additional pen = Rs.95
1 pen = 95

If shopkeeper sells each pen for Rs.10, then 11*10 = 110
Profit = 110-95=15
Percentage = 15*100/95 = 15.789 = 15.8 (Approx.)

priyanka burnwal   9 years AGO

cp of 10 pen is 95
so cp of 1=95/10=9.5
when 1 additional pen is added then ther is 11 pen which is been sold in 95 rs
so cp of 1 pen=95/11
sp of 1 pen is 10
profit%=((sp-cp)/cp)*100
((10-95/11) /(95/11))*100=15.78=15.8
