  • Question
  • At a simple interest, a sum amounts to ? 1012 in 2 1/ 2 and becomes ? 1067.20 in 4 yr. What is the rate of interest


  • Options
  • A. 2.5%
  • B. 3%
  • C. 4%
  • D. 5%

  • Correct Answer
  • 4% 

    Explanation

    Given, T1 = 21/2 yr, T2 = 4 Yr

    According to the question.
    [P + (P x R x 4)/100] - [P + (P x R x 2.5)/100] = 1067.20 - 1012 = 55.2
    ? (1.5 x P x R)/100 = 55.2
    ? PR = (552 x 100) / 15 = 3680

    For 4 yr.
    SI = PRT/100 = (3680 x 4)/100 = ? 147.2
    ? Sum (P) = 1067.2 - 147.2 = ? 920
    We have, PR = 3680
    ? R = 3680/P = 3680/920 = 4%
