A dozen pens are sold for Rs. 480 at a profit of Rs. 120. What is the cost of all the pend?What is the cost price of each pen?

Answer»

of 12 pens(a DOZEN) = 120

selling price of 1 pen = 15

selling price of 12 pens = 12*15 = 180

profit = sp - cp = 180 - 120 = 60

profit % = profit / cp * 100

= 60/120*100

= 50%
