Question

A bookseller procures $40$ books for $3200$ 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. $1440$

Answer 1

Answer: (C)

$1200$

Let selling price of each book is $X$

SP of 40 books $=40X$

SP of 8 books$=8X$

According to the Question

Total SP $-$ Total Profit = CP

$40X-8X=3200$

$32X=3200$

$X=100$

SP of each book is $100$

∴∴ SP of one dozen books $=12\times 100=Rs1200$
