Show answer & explanation
Correct answer: A
Solution: Step-by-step
Key point: 3 paise per rupee per month = 3% per month (because 100 paise = 1 rupee).
Principal P = Rs 10
Rate R = 3% per month
Time T = 4 months
Formula: SI = P × R × T / 100
Calculation: SI = 10 × 3 × 4 / 100 = 120 / 100 = Rs 1.20
Answer: The simple interest for 4 months is Rs 1.20.
