Download Solution PDFदिया है:
मूलधन = 1200 रुपये
दर = R = 4%
प्रयुक्त सूत्र:
A = P [1 + (R/100)]t
गणना:
माना, अवधि = n वर्ष
⇒ 2400 = 1200[1 + (4/100)]n
⇒ 2 = [1 + ((4/100)]n
⇒ 2 = [104/100]n
⇒ 2 = [1.04]n
दोनों तरफ लघुगुणक करने पर,
⇒ log 2 = log [1.04]n
⇒ log 2 = n × log [1.04]
⇒ n = log 2/log 1.04 = 17.67
∴ विकल्प 2 सही उत्तर है।
