दिया गया है:

मूलधन (P) = 10,000 रुपये

दर (R) = 10% प्रति वर्ष

समय (T) = 2 वर्ष

प्रयुक्त अवधारणा:

मिश्रधन \(P(1+\frac{r}{100})^t\)

गणना:

⇒ 2 वर्ष बाद मिश्रधन = 10000 × \((1+\frac{10}{100})^2\)

= 10000 × \(\frac{110}{100}\times \frac{110}{100}\)

= 110 × 110 = 12,100 रुपये

इसलिए, 2 वर्ष बाद नरेश द्वारा प्राप्त कुल राशि 12,100 रुपये है।

अत:, सही उत्तर विकल्प 4) है।
