How much time will it take for an amount of Rs. 450 to yield Rs. 81 as interest at 4.5% per annum of simple interest?
A 2 years
B 3 years
C 4 years
D 5 years
Correct Answer: 4 years
Explanation:

  • Let's use the simple interest formula:
  • Simple Interest (SI) = (Principal x Rate x Time)/100
  • Given: Principal (P) = Rs 450
  • SI = Rs 81
  • Rate (R) = 4.5% per annum
  • We need to find Time (T). Rearranging the formula
  • 81 = (450 * 4.5 *T) / 100
  • Multiply both sides by 100:
  • 8100 = 450 * 4.5 * T
  • 8100 = 2025 * T
  • Divide both sides by 2025:
  • T = 8100/2025
  • T = 4
  • The correct answer is: (C) 4 years
