2 वर्ष बाद चक्रवृद्धि ब्याज = रु. 1,908
ब्याज दर = 12% प्रति वर्ष
अवधारणा:
CI = P [(1 + r/100)t - 1]
समाधान:
CI = P [(1 + r/100)t - 1]
⇒ 1908 = P [(1 + 12/100)2 - 1]
⇒ 1908 = P [(1 + 3/25)2 - 1]
⇒ 1908 = P [(28/25)2 - 1]
⇒ 1908 = P [784/625 - 1]
⇒ 1908 = P × 159 / 625
⇒ P = 1908 × 625 / 159
⇒ P = 12 × 625 = रु. 7500
अतः मूलधन 7,500 रुपये है।
