Question

Joy brought pens at ₹120 a dozen . He sold it for ₹15 each. What is his profit per cent

Answer 1

Answer:

Step-by-step explanation:

here,

           selling price of pen=RS 120

            cost price of pen =RS 15

                    since,s.p is greater than c.p, there is profit

                                    therefore,  

                                                                profit=S.P-C.P.

                                                                         =RS 120-RS 15

                                                                          =RS 105

Answer 2

Answer:

Dozen = 12 things

cost of 12 pens brought Joy = Rs.120

cost of each= cost of pens/number of pens

                   = Rs.120/12

                   = Rs.10

Hence,the of each pen is Rs.10

sold price for each pen by him = Rs.15

total cost of one dozen(12) pens = Rs.15×12

                                                      = Rs.180

profit earned by Joy =  sold price - pervious price

                                  = Rs.180 - Rs.120

                                  = Rs.60

Hence, profit price earned by him = Rs.60

profit percentage = amount of change/original amount × 100

                             = 60/120 × 100

                             = 50%

Hence, Joy earned 50% profit by solding pens
