  • Question
  • A sum of ? 2668 amount to ? 4669 in 5 yr at the rate of simple interest . Find the rate per cent.


  • Options
  • A. 15.2%
  • B. 14.9%
  • C. 16%
  • D. 15%

  • Correct Answer
  • 15% 

    Explanation

    Here, P = ? 2668, T = 5 yr, A = ? 4669
    We know that,
    Amount (A) = Principal (P) + (Simple Interest) SI
    4669 = 2668 + SI
    ? SI = 4669 - 2668 = ? 2001
    Again, SI = (P x R x T)/100
    ? 2001 = (2668 x R x 5)/100
    ? R= (2001 x 100) / (2668 x 5)
    = (2001 x 5)/667
    = 15%
