    Question

    The question consists of 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. What is the area of rectangle ABCD? Statement I : Perimeter of rectangle ABCD is 4.5 times of its breadth. Statement II : Difference between squares of adjacent pair of sides of rectangle ABCD is 5.4 times its breadth.  
    A From both I and II Correct Answer Incorrect Answer
    B Either I or II Correct Answer Incorrect Answer
    C only I Correct Answer Incorrect Answer
    D Only II Correct Answer Incorrect Answer
    E Neither I nor II Correct Answer Incorrect Answer

    Solution

    From Statement I: 2 (l + b) = 9/2 b => l + b = 9/4 b => l = 5b/4 From Statement II: l2 – b2 = 27/5 b Combining statements I and II we will get the area of rectangle ABCD. Therefore, both the statements are required to answer the question.
