Q. Which formula gives the simple interest (SI) on a principal P at rate R% for T years?

  • (A) SI = P + R + T
  • (B) SI = (P × R) + T
  • (C) SI = (P × R × T) / 100
  • (D) SI = P × (1 + R/100)^T
✅ Correct Answer: (C) SI = (P × R × T) / 100
Explanation: Correct: SI = (P × R × T) / 100 is the standard simple interest formula. Option1 and Option2 are dimensionally wrong. Option4 is the compound interest formula, not simple interest.
