    B Rs.15000 Correct Answer Incorrect Answer
    C Rs20000 Correct Answer Incorrect Answer
    D Rs.35000 Correct Answer Incorrect Answer

    Solution

    ATQ, Let the sum borrowed by A be x and by B be y Interest paid by A = [I × A] = x × 4 × (5/100) and Interest paid by B = [I × B]= y × 5 × (4/100) Since interest paid by A is double that of B's; [I × A] = 2(I × B) =>​ (x/5) = (2y/5) =>​ x = 2y x + y =30000 =>​ ​2y + y = 30000  =>​ y = 10000. Therefore, x = 20,000 Sum borrowed by A is Rs.20000
