Question

C) a dozen books are sold at ₹1,648 at a profit of ₹120. what is the cost price of the books,

Answer 1

Answer:

₹ 1528

Step-by-step explanation:

selling price = ₹ 1648

profit gained = ₹ 120

profit = selling price - cost price

cost price = selling price - profit

                 = 1648 - 120

                 = ₹ 1528

cost of single book can also be found by dividing it with number of books. here it is 12,

C.P. of 1 book = 1528/12

                       = ₹ 127.3
