  • Question
  • The value of a machine depreciates at the rate of 10% every year. It was purchased 3 years ago. If its present value is Rs. 8,748, its purchase price was ?


  • Options
  • A. Rs.14,000
  • B. Rs.12,000
  • C. Rs. 12,800
  • D. Rs. 15,000

  • Correct Answer
  • Rs.12,000 

    Explanation

    We have P = 8748, R = -10 and n = 3
    Therefore, the purchase price of the machine
    = P 1 + R 100 n = 8748 1 - 10 100 3
    = 8748 x (100/90) x (100/90) x (100/90)
    = 12,000.

     

    Therefore, the purchase price of the machine was Rs. 12,000.
