An amount of Rs. 6500, at simple quarterly interest of 8%, will yield how much in 2 and half years?

Answer: D

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

The rate is 8% per annum and the period two and a half years.

\[ \text{SI} = \frac{6500 \times 8 \times 2.5}{100} = \text{Rs. } 1300 \]

\[ \text{amount} = 6500 + 1300 = \text{Rs. } 7800 \]

The question asks what the sum will yield in total, so the principal is included; the interest alone is Rs. 1300.
