साधारण ब्याज पर निवेश की गई कोई राशि 2 वर्ष 6 महीने में स्वयं की 17/10 हो जाती है।
प्रयुक्त अवधारणा:
साधारण ब्याज = (मूलधन × समय × दर)/100
गणना:
मान लीजिए निवेश की गई राशि a है और ब्याज की दर r है।
निवेश की अवधि = 2 वर्ष 6 माह = 2.5 वर्ष
इसलिए,
(a × r × 2.5)/100 = ar/40
प्रश्नानुसार,
राशि = (17/10) × निवेश की गई धनराशि
⇒ (ar/40) + a = (17/10) × a
⇒ (r + 40)/40 = 17/10
⇒ r + 40 = 68
⇒ r = 28
इसलिए, दर = 28%
∴ वार्षिक ब्याज दर 28% है।
