प्रति वर्ष 8% साधारण ब्याज पर कोई धनराशि \(3\frac{1}{2}\) अर्थात 3.5 वर्षों में 608 रुपये हो जाती है।
प्रयुक्त अवधारणा:
साधारण ब्याज, SI = (P × R × T)/100
मिश्रधन = P + SI
जहाँ,
P = मूलधन
R = प्रति वर्ष ब्याज की दर
T = समय, वर्षों में
गणना:
माना निवेश की गई राशि P है।
प्रश्नानुसार,
P + (P × 8 × 3.5)/100 = 608
⇒ P + 0.28P = 608
⇒ 1.28P = 608
⇒ P = 608/1.28
⇒ P = 475
∴ निवेश की गई राशि 475 रुपये है।
