    Directions: in each of the given questions, one question and two statements numbered I and II are given. You have to decide whether the data given in both the statements are sufficient to answer the question or not. Read both statements and give answer.
    What is the cost of painting two adjacent walls of a hail having no door or window at \[Rs.\,450\,per\,{{m}^{2}}\]?
    I. Length and breadth are in the ratio of 3: 2 respectively
    II. Perimeter of the halt is 50 m and height is one fourth of the perimeter.

    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 statemant II alone are sufficient to answer the question

    D) If the data in both statements I and II together are not sufficient 10 answer the question

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

    Correct Answer: E

    Solution :

    From statement I,
    Length: Breadth
    \[\begin{matrix}    \begin{align}   & =3:2 \\  & \,\,\,\,\,\,\downarrow  \\ \end{align}  \\    3x:2x  \\ \end{matrix}\]
    From statement II,
    Height \[=50\times \frac{1}{4}=12.5\]
    Perimeter\[=2\,(3x+2x)=50\]
                \[\Rightarrow \]   \[x=5\]
    So, area of two any adjacent walls \[=lh+bh\]
    Total cost of painting on wall \[=12.5\times 25\times 450\]
                                        \[=Rs.140625\]
