दिलेल्याप्रमाणे:

मुद्दल (P) = 12,000 रुपये 

रास (A) = 14,520 रुपये 

दर (r) = 10% वार्षिक

वापरलेले सूत्र:

A = P(1 + \(\frac{r}{100}\))t

गणना:

14,520 = 12,000(1 + \(\frac{10}{100}\))t

\(\frac{14,520}{12,000}\) = (1 + \(\frac{10}{100}\))t

⇒ 1.21 = (1.1)t

⇒ 1.12 = (1.1)t

⇒ t = 2

म्हणूनच योग्य उत्तर पर्याय (1) आहे.
