Correct answer: (A) ₹15,840₹15,840

Explanation

15972/12000 = 1.331 = (1.1)³, so the half-yearly rate is 10% and the annual rate 20%. Compounded annually for 1 1/2 years: 12000 × 1.2 × 1.1 = ₹15,840.15972/12000 = 1.331 = (1.1)³, इसलिए अर्धवार्षिक दर 10% और वार्षिक दर 20% है। 1 1/2 वर्ष के लिए वार्षिक संयोजन पर: 12000 × 1.2 × 1.1 = ₹15,840।
