Correct answer: C. Rs. 10.0010.00 रुपये

Explanation

For 2 years, CI − SI = P × (R/100)² = 4000 × (5/100)² = 4000 × 1/400 = Rs. 10. (Check: SI = 400, CI = 4000(1.05² − 1) = 410.)2 वर्ष के लिए CI − SI = P × (R/100)² = 4000 × (5/100)² = 4000 × 1/400 = 10 रुपये। (जाँच: SI = 400, CI = 4000(1.05² − 1) = 410।)
