Download Solution PDFदिया गया है:
समय (t) = 4 वर्ष
मिश्रधन = मूलधन (P) का 2 गुना
प्रयुक्त सूत्र:
साधारण ब्याज (SI) = (P × r × t)/100
जहाँ, SI = मिश्रधन - मूलधन (P)
गणना:
मिश्रधन = मूलधन (P) का 2 गुना
⇒ SI = मूलधन (P)
⇒ मूलधन (P) × r × t/100 = मूलधन (P)
⇒ r × t = 100
⇒ r × 4 = 100
⇒ r = 100/4
⇒ r = 25%
∴ सही उत्तर विकल्प (3) है।
