एक रक्कम 3 वर्षांत 7,800 रुपये आणि 5 वर्षांत 11,232 रुपये होते.
वापरलेले सूत्र:
चक्रवाढ व्याजासाठी, अंतिम रास =
येथे, P = मुद्दल
r = व्याजाचा दर
n = मुदत (वर्षे)
गणना:
येथे, चक्रवाढ व्याजाने 7800 रुपयांचे दोन वर्षांत 11232 रुपये होतात.
समजा, व्याजाचा दर = R
म्हणून, 11232 =
⇒ [(100 + R)/100]2 = 11232/7800
⇒ [(100 + R)/100]2 = 144/100
⇒ [(100 + R)/100]2 = (12/10)2
⇒ [(100 + R)/100] = (12/10)
⇒ 100 + R = 1200/10 = 120
⇒ R = 120 - 100 = 20
∴ व्याजदराची टक्केवारी = 20%
