    What is the area of circle? I. The radius of the

    circle is one third the length of a rectangle and the breadth of the rectangle is one third the length of the rectangle. II. The radius of the circle is equal to the sides of the square. III. The area of the square is 1024 sq cm.

    B Only I and III Correct Answer Incorrect Answer
    C Only II and III Correct Answer Incorrect Answer
    D Any two of them Correct Answer Incorrect Answer
    E All are together are necessary Correct Answer Incorrect Answer

    Solution

    We can find the area of circle. But from I we cannot find the radius of the circle. From III, the side of the square can be found out and combining it with II, we can find the area of the circle. Hence, only II and III are necessarily to answer.
