A and B together borrowed a sum of ₹51,750 at an interest rate of 7%p.a. compound interest in such a way that to settle the loan, A paid as much amount after three years as paid by B after 4 years from the day of borrowing. The sum (in ₹) borrowed by B was:
$$\frac{x^2(x - 4)^2}{(x + 4)^2 - 4x} \div \frac{(x^2 - 4x)^3}{(x + 4)^2} \times \frac{64 - x^3}{16 - x^2}$$ is equal to
