Ques - A bookseller procures 40 books for Rs. 3200 and sells them at a profit equal to the selling price of 8 books. What is the selling price of one dozen books, if the price of each book is same?
(a) 720
(b) 960
(c) 1200
(d) 1440
Solution -
CP of 40 books = 3200
CP of 1 book = 80
Now,
SP of 40 books = CP of 40 books + SP of 8 books
SP of 40 books - SP of 8 books = CP of 40 books
SP of 32 books = 3200
SP of 1 book = 3200/32
SP of 1 book = 100
SP of 12 books (1 dozen) = 12 × 100
= 1200
Therefore,
The selling price of 1 dozen books is Rs. 1200.
Hence,
The correct answer is option (c) 1200.
