1.
साधारण ब्याज पर निवेश की गई कोई धनराशि 5 वर्षों में ₹21,500 और 8 वर्षों में ₹26,000 हो जाती है। मूलधन (₹ में) ज्ञात कीजिए।
A sum of money invested at simple interest amounts to ₹21,500 in 5 years and ₹26,000 in 8 years. Find the principal amount (in ₹).
- (A)15,500
- (B)12,000
- (C)7,500
- (D)14,000
Show answer and explanation
Answer: (D)
14,000
3 वर्ष का ब्याज = 26,000 − 21,500 = 4,500, अतः प्रति वर्ष साधारण ब्याज = 1,500। 5 वर्ष का ब्याज = 7,500। मूलधन = 21,500 − 7,500 = 14,000। अतः उत्तर 14,000 है।
Interest for 3 years = 26,000 − 21,500 = 4,500, so SI per year = 1,500. Interest for 5 years = 7,500. Principal = 21,500 − 7,500 = 14,000. So the answer is 14,000.

₹5,70,000 की धनराशि पर 10% वार्षिक ब्याज दर से 1.5 वर्ष का चक्रवृद्धि ब्याज ज्ञात कीजिए, जहां ब्याज अर्धवार्षिक रूप से संयोजित होता है।
Find the compound interest on ₹5,70,000 for 1.5 years at 10% per annum compounded half-yearly.
- (A)₹89,846.25
- (B)₹89,946.25
- (C)₹88,846.25
- (D)₹92,846.25
Show answer and explanation
Answer: (A)
₹89,846.25
अर्धवार्षिक दर = 5%, अवधियाँ = 3। मिश्रधन = 5,70,000 × 1.05³ = 5,70,000 × 1.157625 = 6,59,846.25। चक्रवृद्धि ब्याज = 6,59,846.25 − 5,70,000 = 89,846.25। अतः उत्तर ₹89,846.25 है।
Half-yearly rate = 5%, periods = 3. Amount = 5,70,000 × 1.05³ = 5,70,000 × 1.157625 = 6,59,846.25. CI = 6,59,846.25 − 5,70,000 = 89,846.25. So the answer is ₹89,846.25.
3.
यदि किसी आयताकार क्षेत्र की लंबाई 120 मीटर और चौड़ाई 75 मीटर मापी जाती है, तो उसका क्षेत्रफल SI मात्रक में कितना होगा?
If the length of a rectangular field is measured as 120 metres and its width as 75 metres, what will be its area in SI units?
- (A)15000 वर्ग मीटर15000 square metres
- (B)1800 वर्ग मीटर1800 square metres
- (C)19500 वर्ग मीटर19500 square metres
- (D)9000 वर्ग मीटर9000 square metres
Show answer and explanation
Answer: (D)
9000 वर्ग मीटर
9000 square metres
आयत का क्षेत्रफल = लंबाई × चौड़ाई = 120 × 75 = 9000 m²। अतः उत्तर 9000 वर्ग मीटर है।
Area of rectangle = length × width = 120 × 75 = 9000 m². So the answer is 9000 square metres.
