Correct answer: (B) 363
SI for 2 years = ₹66 ⟹ Pr = 3300 (where r is in %). The CI−SI difference for 2 years equals P(r/100)² = 3, so P = 3300²/(3×100²)... simplified: P = 33²/(diff) = 1089/3 = 363.

सही उत्तर: (B) 363
2 वर्ष के लिए SI = ₹66 ⟹ Pr = 3300 (r प्रतिशत में)। 2 वर्ष के लिए CI−SI का अंतर P(r/100)² = 3 होता है, इसलिए P = 33²/3 = 1089/3 = 363।
