    Question

    What is the area of a circular field? I. The area

    of the largest square that can be inscribed in the given circular field is 450 cm┬▓. II. The area of the smallest square in which the given circular field can be inscribed is 900 cm┬▓. Each of the questions below consists of a question and three statements numbered I and II given below it. You have to decide whether the data provided in both the statements are sufficient to answer the question. Read all the statements and give answer тАУ
    A If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question. Correct Answer Incorrect Answer
    B If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question. Correct Answer Incorrect Answer
    C If the data either in statement I alone or in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D If the data in both statements I and II together are necessary to answer the question. Correct Answer Incorrect Answer
    E If the data even in both statements I and II together are not sufficient to answer the question. Correct Answer Incorrect Answer

    Solution

    From I, Area of largest square inscribed in a circle of radius r is 2r┬▓. Then, 2r┬▓ = 450 тИ┤ r = тИЪ225 = 15 cm Thus we can find the area of the circular field. Hence I alone is sufficient to answer the question. From II. Area of the smallest square in which a circle can be inscribed = 4r┬▓. Then, 4r┬▓ = 900 тИ┤ r┬▓ = тИЪ225 = 15 cm Thus we can find the area of the circular field. Hence II alone is sufficient to answer the question.
