    Directions: Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and given answer.                                                                                                                       [SBI (S0)2014]
    What will be the amount at the end of 2 yr, if the interest is compounded yearly.
    I. The simple interest on the same sum for a period of 2 yr is Rs. 400 at the same rate of 5% per annum.
    II. The difference between the simple interest and the compound interest for 2 yr at the rate of 5% per annum is Rs. 100.

    A) If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question

    B) If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question

    C) If the data either in statement I alone or in statement II alone are sufficient to answer the question

    D) If the data given in both the statements I and II together are not sufficient to answer the question

    E) If the data in both the statements I and II together are necessary to answer the question

    Correct Answer: C

    Solution :

    From statement I,
    \[P=\frac{SI\times 100}{R\times T}=\frac{400\times 100}{5\times 2}=\text{Rs}\text{. 4000}\]
    Using \[A={{\left( 1+\frac{R}{100} \right)}^{T}},\]amount can be determined.
    From statement II,
                            \[\text{Difference}=\frac{{{\operatorname{PR}}^{2}}}{{{(100)}^{2}}}\]
    We can find principal and hence amount.
