चक्रवाढ व्याज 3 वर्षांच्या गुंतवणूकीत 4 पट होते.
संकल्पना:
चक्रवाढ व्याजाची संकल्पना.
वापरलेले सूत्र:
रक्कम = P × (1 + R/100)T
जेथे, P = मुद्दल, R = दर, T = मुदत
हिशोब:
समजा मुद्दल = रु. P
⇒ 3 वर्षांनंतरची रक्कम = 4 P
प्रश्नानुसार,
4P = P × (1 + R/100)3
⇒ (1 + R/100)3 = 4 ----(i)
आता,
A = 16 P, वेळ = T (समजा)
⇒ 16P = P × (1 + R/100)T
⇒ (1 + R/100)T = 16 = 42
समीकरणावरून (i):
(1 + R/100)T = (1 + R/100)6
⇒ T = 6
∴ रक्कम 6 वर्षांत 16 पट होईल.
