Sample Simple Interest & Compound Interest questions with answers

Q1. What is the simple interest on ₹5,000 at 8% per annum for 3 years?

₹5,000 पर 8% वार्षिक दर से 3 वर्ष का साधारण ब्याज क्या होगा?

₹1,000
₹1,200
₹1,400
₹1,500

Answer: ₹1,200. SI = (P × R × T) ÷ 100 = (5000 × 8 × 3) ÷ 100 = ₹1,200.
साधारण ब्याज = (P × R × T) ÷ 100 = (5000 × 8 × 3) ÷ 100 = ₹1,200

Q2. Find the compound interest on ₹1,000 at 10% per annum for 2 years (compounded yearly).

₹1,000 पर 10% वार्षिक दर से 2 वर्ष का चक्रवृद्धि ब्याज ज्ञात करें (वार्षिक संयोजन)।

₹210
₹200
₹211
₹220

Answer: ₹210. Amount = 1000 × (1 + 10/100)² = ₹1,210. CI = 1210 − 1000 = ₹210.
मिश्रधन = 1000 × (1 + 10/100)² = ₹1,210। चक्रवृद्धि ब्याज = 1210 − 1000 = ₹210

Q3. Find the compound interest on ₹10,000 at 5% per annum for 2 years (compounded yearly).

₹10,000 पर 5% वार्षिक दर से 2 वर्ष का चक्रवृद्धि ब्याज ज्ञात करें (वार्षिक संयोजन)।

₹1,025
₹1,000
₹1,125
₹975

Answer: ₹1,025. Amount = 10000 × (1 + 5/100)² = ₹11,025. CI = 11025 − 10000 = ₹1,025.
मिश्रधन = 10000 × (1 + 5/100)² = ₹11,025। चक्रवृद्धि ब्याज = 11025 − 10000 = ₹1,025

Q4. Find the simple interest on ₹3,000 at 5% per annum for 6 years.

₹3,000 पर 5% वार्षिक दर से 6 वर्ष का साधारण ब्याज ज्ञात करें।

₹900
₹1,800
₹1,050
₹150

Answer: ₹900. SI = 3000 × 5 × 6/100 = ₹900.
साधारण ब्याज = 3000 × 5 × 6/100 = ₹900

Q5. What is the difference between compound interest and simple interest on ₹5,000 for 2 years at 10% per annum?

₹5,000 पर 10% वार्षिक दर से 2 वर्ष के चक्रवृद्धि और साधारण ब्याज का अंतर क्या है?

₹50
₹500
₹60
₹100

Answer: ₹50. Difference for 2 years = P × (R/100)² = 5000 × (10/100)² = ₹50.
2 वर्ष का अंतर = P × (R/100)² = 5000 × (10/100)² = ₹50

Q6. What is the difference between compound interest and simple interest on ₹19,000 for 2 years at 20% per annum?

₹19,000 पर 20% वार्षिक दर से 2 वर्ष के चक्रवृद्धि और साधारण ब्याज का अंतर क्या है?

₹1,520
₹770
₹760
₹3,800

Answer: ₹760. Difference for 2 years = P × (R/100)² = 19000 × (20/100)² = ₹760.
2 वर्ष का अंतर = P × (R/100)² = 19000 × (20/100)² = ₹760

Q7. Find the simple interest on ₹8,000 at 12% per annum for 4 years.

₹8,000 पर 12% वार्षिक दर से 4 वर्ष का साधारण ब्याज ज्ञात करें।

₹960
₹4,800
₹7,680
₹3,840

Answer: ₹3,840. SI = (P × R × T)/100 = (8000 × 12 × 4)/100 = ₹3,840.
साधारण ब्याज = (P × R × T)/100 = (8000 × 12 × 4)/100 = ₹3,840

Q8. Find the simple interest on ₹2,000 at 4% per annum for 4 years.

₹2,000 पर 4% वार्षिक दर से 4 वर्ष का साधारण ब्याज ज्ञात करें।

₹400
₹320
₹80
₹640

Answer: ₹320. SI = (P × R × T)/100 = (2000 × 4 × 4)/100 = ₹320.
साधारण ब्याज = (P × R × T)/100 = (2000 × 4 × 4)/100 = ₹320

Q9. A sum of ₹19,000 earns ₹3,420 as simple interest in 3 years. What is the rate of interest per annum?

₹19,000 पर 3 वर्ष में ₹3,420 साधारण ब्याज मिलता है। वार्षिक ब्याज दर क्या है?

Answer: 6%. R = SI × 100/(P × T) = 3,420 × 100/(19,000 × 3) = 6%.
R = SI × 100/(P × T) = 3,420 × 100/(19,000 × 3) = 6%।

Q10. A sum of ₹18,000 earns ₹4,500 as simple interest in 5 years. What is the rate of interest per annum?

₹18,000 पर 5 वर्ष में ₹4,500 साधारण ब्याज मिलता है। वार्षिक ब्याज दर क्या है?

Answer: 5%. R = SI × 100/(P × T) = 4,500 × 100/(18,000 × 5) = 5%.
R = SI × 100/(P × T) = 4,500 × 100/(18,000 × 5) = 5%।
