A retailer buys 40 pens at the marked price of 36 pens from a wholesaler. If he sells these pens giving a discount of 1%, what is the profit percent
1). 9%
2). 10%
3). $10\frac{1}{9}$ %
4). 11 %
Let MP of $1$ Pen = Rs. $1 $
CP of $40$ pen = Rs. $36$
SP of $40$ pen = $( \Large 40 \times \frac{99}{100} = Rs. 39.6 )$
Profit $% =$ $( \Large \frac{39.6 - 36}{36} \times 100 = 10% )$
