Detailed Solution & Logic
Correct Answer:
Rs. 6,408
Given:
Amount $A = 7200$, rate $r = 6%$, time $t = 2$ years
Step 1: Compound interest formula
$A = P(1 + \frac{r}{100})^t$
$7200 = P(1.06)^2$
$7200 = P \times 1.1236$
Step 2: Solve for $P$
$P = \frac{7200}{1.1236}$
$P \approx 6406.6$
Step 3: Round off
$P \approx 6407$
Closest option = 6408
Final Answer: Rs. 6408
