A sum of money becomes 240% of itself in 8 years at simple interest. Find the simple interest earned when Rs. 3000 is invested at the same rate for 3 years.
Rs. 1620
Rs. 1430
Rs. 1255
Rs. 1575
Answer: D
The interest earned in 8 years is 240% − 100% = 140% of the principal. Annual rate = 140/8 = 17.5%. Simple interest for 3 years = (3000 × 17.5 × 3)/100 = ₹1,575.
एक धनराशि साधारण ब्याज पर 8 वर्ष में स्वयं की 240% हो जाती है। 3000 रुपये को उसी दर पर 3 वर्षों के लिए निवेश करने पर अर्जित साधारण ब्याज ज्ञात कीजिए।
1620 रुपये
1430 रुपये
1255 रुपये
1575 रुपये
उत्तर: D
8 वर्षों का ब्याज = 240% − 100% = मूलधन का 140%। वार्षिक ब्याज दर = 140/8 = 17.5%। 3 वर्षों का साधारण ब्याज = (3000 × 17.5 × 3)/100 = ₹1,575।
