Burak and Ceyda each borrowed TL X at t = 0. Burak paid 1.900 TL at the end of the 10th year and Ceyda paid 2.400 TL at the end of the 10th year and paid their debts. Find the cumulative value of Burak's debt at the end of the second year, since the six-month effective interest rate of Burak's debt is half of the six-month effective interest rate of Ceyda's debt.
