  • B. Rs. 548.68
  • C. Rs. 445.95
  • D. Rs. 692.57

  • Correct Answer
  • Rs. 445.95 

    Explanation

    We know Compound Interest = C.I. = P1+r100t - 1

    Here P = 2680, r = 8 and t = 2

    C.I. = 26801 + 81002-1= 268027252-12= 26802725+12725-1= 2680 5225×225

    = (2680 x 52 x 2)/625

    = 445.95

     

    Compound Interest = Rs. 445.95
