एक व्यक्ति साधारण ब्याज पर कुछ धनराशि उधार लेता है। 4 वर्षों के बाद, वह ऋणदाता को धनराशि का \(\frac{9}{5}\) भाग वापस कर देता है।
प्रयुक्त सूत्र:
साधारण ब्याज = P × R × T / 100 [P = मूलधन, R = ब्याज दर, T = समय]
गणना:
मान लीजिए, R = ब्याज दर
मूलधन = P
व्यक्ति को प्राप्त साधारण ब्याज है:
⇒ 9P/5 - P = 4P/5
सूत्र के अनुसार,
⇒ 4P/5 = P × 4 × R / 100
⇒ R = 20%
∴ सही उत्तर विकल्प 4 है।
