Correct answer: (A) 1089
For 2 years, CI - SI = P(R/100)2 and SI = 2PR/100. Given SI=66 so PR/100=33, and CI-SI=1 so (PR/100)(R/100)=1, giving R/100 = 1/33. Then P = 33 x 33 = ₹1089.

सही उत्तर: (A) 1089
2 वर्ष के लिए CI - SI = P(R/100)2 और SI = 2PR/100 होता है। SI=66 से PR/100=33 मिलता है, और CI-SI=1 से (PR/100)(R/100)=1, अतः R/100 = 1/33। इस प्रकार P = 33 x 33 = ₹1089।
