1. Given:
- Principal (P) =600
- Time (T) =5
- Simple Interest (SI) =60
2. Formula for Simple Interest:
SI = P \times R \times T
3. Rearrange the formula to solve for the annual interest rate (R):
R = \frac{SI}{P \times T}
4. Substitute the given values:
R = \frac{60}{600 \times 5} = \frac{60}{3000} = 0.02
5. Convert to percentage:
R = 0.02 \times 100 = 2\%
Answer:2\%
