Simple Interest Questions and Answers : Quantitative Aptitude

  • A man borrowed some amount, after 3 years he paid Rs.10,400/- with 10% interest, then how much Amount he borrowed?

    A.) Rs.7000/- B.) Rs.8000/-
    C.) Rs.9000/- D.) Rs.1000/-
    Answer: Option 'B'

    principal P = ?
    Rate of interest R = 10%
    Time T = 3 years
    Accumulated Amount A = Rs.10400/-

    A = P + I
    A = P + PTR/100
    A = P(1+ TR/100)

    Rs.10400/- = P [1 + 3*10/100]
    Rs.10400/- = P [1/1 + 3/10]
    Rs.10400/- = P [10+3/10] = P[13/10]
    Rs.10400/- = P * 13/10
    ==> P = Rs.104000/13
    ==> P = Rs.8000/-

    2 years ---------> Rs.1000/-
    1 year ----------> Rs.500/-
    3years * Rs.500/- = Rs.1500/-
    P = Rs.4000/- - Rs.1500/- = Rs.2500/-
    P = Rs.2500/-
