Download Solution PDFदिया गया है:
मिश्रधन (A) = ₹41,160
दर (r) = 40% प्रति वर्ष
समय (t) = 3 वर्ष
प्रयुक्त सूत्र:
A = P(1 + \(\frac{r}{100}\))t
जहाँ, P = मूलधन
गणना:
41,160 = P(1 + \(\frac{40}{100}\))3
⇒ 41,160 = P(1.4)3
⇒ 41,160 = P × 2.744
⇒ P = \(\frac{41,160}{2.744}\)
⇒ P ≈ 15,000
∴ सही उत्तर विकल्प 2 है।
