    Question

    What will be the compound interest earned on a sum in

    two years? I. The simple interest on the same amount at the same rate of interest in two years is Rs. 800. II. The amount becomes more than double at compound interest in 10 years. III. The simple interest on the same amount at the same rate of interest in three years is Rs. 1,200.
    A I and II together or only III alone Correct Answer Incorrect Answer
    B Only I and III Correct Answer Incorrect Answer
    C Only I and II Correct Answer Incorrect Answer
    D All I, II and III Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    From (I) & (III), SI for 1 year = Rs. 400 ∴ 400 = P × R × 1/100 From this we cannot get the answer and also statement II is not sufficient to answer the question.
