What amount does Kiran get if he invests Rs. 18000 at 15% p.a. simple interest for four years?

  • A.Rs. 24800
  • B.Rs. 28400
  • C.Rs. 24400
  • D.Rs. 28800

Answer: D

\[ \text{SI} = \frac{P \times R \times T}{100} \]

\[ \text{SI} = \frac{18000 \times 15 \times 4}{100} = \text{Rs. } 10{,}800 \]

\[ \text{amount} = 18000 + 10800 = \text{Rs. } 28{,}800 \]

The question asks what Kiran gets, so the principal is included; the interest alone is Rs. 10,800.
