  • Question
  • If the interest of a certain sum for the first year at 8% p.a. compound interest is Rs. 48. What will be the interest for the second years?


  • Options
  • A. Rs. 52.55
  • B. Rs. 51.84
  • C. Rs. 58.60
  • D. Rs. 53.04

  • Correct Answer
  • Rs. 51.84 

    Explanation

    S.I. or C.I. for first year are always equal
    Principle = (S.I. x 100)/(Rate x Time)
    = (48 x 100)/(8 x 1) = Rs. 600
    Interest for second year = Amount of second year - Amount of the first year
    = 600 (1 +8/100)2 - 600(1 +8/100)
    = 600(27/25)2 - 600(27/25)
    = 600(27/25) {27/25 - 1}
    = 600(27/25) (2/25)
    = Rs. 51.84
