    Question

    What is the sum of two numbers?   I. Difference between

    the numbers is (1/5)  of their product.   II. Difference between the numbers is 20% of their product 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 –
    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, x – y  =  We cannot get the value of X and Y from this equation. From II, x – y  = 20% of xy  ⟹  x  – y  =  We cannot get the value of X and Y from this equation.
