A1000

B5000

C10000

D15000

Answer:

C. 10000

Read Explanation:

വ്യത്യാസം(D)= P ×R²/100² 100 =P ×10²/100² P = 100 × 10000/100 = 10000 Or ഹരി SI = P×n×R/100 SI = P × 2 × 10/100 = 20P/100 അനസ് തുക = P(1 + R/100)^n A + P= P(1+10/100)² = P(110/100 × 110/100) = 121P/100 CI = 121P/100 - P = 21P/100 കാലാവധി പൂർത്തിയായപ്പോൾ അനസിന് 100 കൂടുതൽ കിട്ടി 21P/100 - 20P/100 = 100 P/100 = 100 P = 100 × 100 = 10000
