      Question

      The market value of a laptop falls by 8% in the first year

      and 15% in the second year. If the value after two years is Rs. 19,320, find the original price.
      A β‚Ή24,700 Correct Answer Incorrect Answer
      B β‚Ή41,656 Correct Answer Incorrect Answer
      C β‚Ή46,600 Correct Answer Incorrect Answer
      D β‚Ή36,656 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Net percentage change = –8% –15% + {[(–8%) Γ— (–15%)]/100}%= –23% + 1.2% = –21.8%

      Let the present value be Rs. β€˜x’

      Then, 78.2% of x = 19320

      Or, 0.782 Γ— x = 19320

      Or, x = 19320 / 0.782 = 24700

      So, the original price of the laptop = Rs. 24,700
