    Question

    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 give answer –

    If diameter of a circle is increased by 25%, what will be

    the area of the circle?   I. Circumference of the circle is 88 m.   II. Area of the circle is 616 sq.m.
    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 given in both statements I and II together is not sufficient to answer the question. Correct Answer Incorrect Answer

    Solution

    From I, 2 r  = 88m ⟹ r =  = 14 m.  d =28 m.  increased d = 125% of 28 = 35 m  increased r = 17.5 m  increased area = r² =  = 962.5m² From II, r² = 616 m² ⟹ r²=  = 196  r = 14 m. d = 28 m. increased d = 125% of 28 = 35 m increased r = 17.5 m increased area = r²=  = 962.5m²
