Q. Which of the following is a correct property of simple interest?
  • (A) Interest each year is calculated on the original principal only.
  • (B) Interest is calculated on principal plus previous interest each year.
  • (C) Interest increases exponentially with time.
  • (D) Rate has no effect on simple interest.
💬 Discuss
✅ Correct Answer: (A) Interest each year is calculated on the original principal only.

Explanation: Correct: in simple interest yearly interest = (P×R)/100 and does not include previous interest. Option2 describes compound interest; Option3 is false for SI; Option4 is false because rate directly affects SI.
