At what rate percent on simple interest will Rs.750 amount to Rs.900 in 5 years?
Answer: C
\[ \text{SI} = \frac{P \times R \times T}{100} \]
\[ \text{SI} = 900 - 750 = \text{Rs. } 150 \]
\[ 150 = \frac{750 \times R \times 5}{100} = 37.5R \]
\[ R = 4\% \]
The Rs. 900 is the amount, so the principal must be subtracted first.
