दिया गया है:

मूलधन (P) = ₹12,000

मिश्रधन (A) = ₹14,520

दर (r) = 10% प्रति वर्ष

प्रयुक्त सूत्र:

A = P(1 + \(\frac{r}{100}\))t

गणना:

14,520 = 12,000(1 + \(\frac{10}{100}\))t

\(\frac{14,520}{12,000}\) = (1 + \(\frac{10}{100}\))t

⇒ 1.21 = (1.1)t

⇒ 1.12 = (1.1)t

⇒ t = 2

अतः सही उत्तर विकल्प (1) है।
