  • Question
  • The price of the book is marked 20% above the C.P. If the marked price of the book is Rs. 180, then what is the cost of the paper used in a single copy of the book?


  • Options
  • A. Rs. 36
  • B. Rs. 37.50
  • C. Rs. 42
  • D. Rs. 44.25

  • Correct Answer
  • Rs. 37.50 

    Explanation
    Clearly, marked price of the book = 120% of C.P.

    Also, cost of paper = 25% of C.P

    Let the cost of paper for a single book be Rs. n.

    Then, 120 : 25 = 180 : n     ⟹     n = Rs. 25 x 180 = Rs. 37.50 .
    120
