Here is your answer
A = Rs 729.60
R = 7%
T = 4 years
P = let P

As we know the formula
A = P (1+RT/100)
$729.60 = p(1 + \frac{7 \times 4}{100} ) \\ 729.60 = p(1 + \frac{7}{25} ) \\ 729.60 = p( \frac{25 + 7}{25} ) \\ 729.60 = p( \frac{32}{25} ) \\ p = \frac{729.60 \times 25}{32} \\ p = 570$
Hence
Principal is Rs 570
