Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. ₹3,180.40.

Amount after 3 years =P(1+R100)n=P\left(1+\frac{R}{100} \right)^n

=8000(1+10100)3=8000\left(1+\frac{10}{100} \right)^3

= 8000 × 110/100 × 110/100 × 110/100

= 10648

SI = (P × R × T)/100

6 months = 1/2 years

SI for next 6 months on ₹10648 = (10648 × 10 × 1/2)/100 = 532.40

Total amount = 10648 + 532.40 = 11180.40

SI = 11180.40 - 8000 = 3180.40
