    A sum of Rs.8000 will amount to Rs.8820 in 2 years if the compound interest is calculated yearly, then rate of interest is?
    Solutions
    Amount = Rs.8820
    Principal = Rs.8000
    A = P (1+r/100)n
    8820 = 8000 (1+r/100)2
    8820/8000 = (1+r/100)2
    441/400 = (1+r/100)2
    21/20 = 1+r/100
    1/20 = r/100
    r = 5%
  • Question 10/10
