Detailed Solution
Download Solution PDFदिलेले आहे:
मुद्दल (P) = 6,000 रुपये
व्याजदर (R) = 10% वार्षिक
अंतिम रक्कम (A) = 28,000 रुपये
वापरलेले सूत्र:
सरळव्याज (SI) = (P × R × T) / 100
रक्कम (A) = मुद्दल + व्याज
गणना:
दर 20 वर्षांनी मुद्दलात व्याज जोडले जात असल्याने, ज्या वर्षात रक्कम 28,000 रुपये होते ती वर्षे म्हणजेच (T) कालावधी आपल्याला शोधावा लागेल.
पहिली 20 वर्षे:
SI 1 = (6000 × 10 × 20) / 100
⇒ SI1 = 12000
20 वर्षांनंतर नवीन मुद्दल = P + SI1
नवीन मुद्दल = 6000 + 12000 = 18000
SI2 = 28000 - 18000 = 10000
SI2 = (18000 × 10 × T)/100
⇒ 10000 = (18000 × 10 × T)/100
⇒ 10000/1800 = T
⇒ T = 20 वर्षे.
एकूण वेळ = 20 वर्षे + 20 वर्षे = 25.55 वर्षे
