(b) ₹2,100
(c) ₹2,200
(d) ₹2,050
(e) ₹2,150
₹10,000 के मूलधन पर 10% वार्षिक ब्याज दर से 2 वर्ष के लिए वार्षिक रूप से संयोजित चक्रवृद्धि ब्याज कितना होगा?
(a) ₹2,000
(b) ₹2,100
(c) ₹2,200
(d) ₹2,050
(e) ₹2,150
Correct Answer: (b)
Explanation:
Amount A = P(1 + R/100)^t = 10,000 (1 + 10/100)² = 10,000 1.21 = ₹12,100.
Compound Interest = A – P = 12,100 – 10,000 = ₹2,100.
मिश्रधन = 10,000 * (1.1)² = ₹12,100।
चक्रवृद्धि ब्याज = 12,100 – 10,000 = ₹2,100। सही उत्तर (b) है।
