    (III) 500, 8333

    A Only (I) Correct Answer Incorrect Answer
    B Only (II) Correct Answer Incorrect Answer
    C Both (II) and (III) Correct Answer Incorrect Answer
    D All (I), (II) and (III) Correct Answer Incorrect Answer
    E Both (I) and (II) Correct Answer Incorrect Answer

    Solution

    Y = 3 [from (i)] From (ii) A = 3 + 5 = 8 Now ATQ, R = T = P = = 10000 + R 2 + 200R - 10000 = R 2 + 200R = 5R 2 4R 2 – 200R = 0 4R(R – 50) = 0 R = 0, 50 Now, R = 50 T = S139. Ans. (1 Sol. From (I), ATQ, Simple interest = Q= 3750 P = So, (I) is possible to fill all the respective fillers. From (II), Simple interest = Q=1250 P = So, (II) is not to fill all the respective fillers. From (III), Simple interest = Q=6250 P = So, (III) is not to fill all the respective fillers.
