Here is your answer
Let the principal is x
For 3 years

SI = PRT/100
$= \frac{x \times 10 \times 3}{100} \\ \\ = \frac{3x}{10}$
For 4 years
SI = PRT/100
$= \frac{x \times 10 \times 4}{100} \\ \\ = \frac{4x}{10}$
ATQ
$\frac{4x}{10} - \frac{3x}{10} = 565 \\ \\ \frac{4x - 3x}{10} = 565 \\ \\ x = 565 \times 10 \\ \\ x = 5650$
Therefore principal is Rs 5650
