The Correct Option is A
Solution and Explanation
- Step 1: Simple interest. SI = $\frac{P \cdot R \cdot T}{100}$, $P = 6000$, $R = 7$, $T = 4$.
- Step 2: Calculate. SI = $\frac{6000 \cdot 7 \cdot 4}{100} = 1680$.
- Step 3: Total amount. $6000 + 1680 = 7120$.
- Step 4: Verify. Yearly interest = $\frac{6000 \cdot 7}{100} = 420$. For 4 years: $420 \cdot 4 = 1680$. Total = $6000 + 1680 = 7120$.
- Step 5: Conclusion. Option (1) 7120 is correct.
