      Question

      Given below is a question followed by two statements

      numbered I and II, each containing some information. Decide which of the statement(s) is/are sufficient to answer the question. What is the value of a? Statements: I. 2a +2b = 4 – 2 (a – b) II. a + 3b = 2a – 2
      A Both statements I and II together are necessary to answer the question. Correct Answer Incorrect Answer
      B Statement II alone is sufficient to answer the question, while statement I alone is not sufficient to answer the question. Correct Answer Incorrect Answer
      C Either statement I alone or statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
      D Statement I alone is sufficient to answer the question, while statement II alone is not sufficient to answer the question. Correct Answer Incorrect Answer

      Solution

      Statement-I 2a + 2b = 4 -2 (a-b) To simplify this expression 2a + 2b = 4 – 2a + 2b Combine 4a = 4 After divide- a=1 So, statement I is sufficient to determine the value of A.
