  1. I do not think option B helps in anyways because it is said that x, y and z are different integers. But it is true that X is 1. But since the X=1 does not suffice the statement, the answer should be c.
    Please correct me if wrong

  2. The answer should be C. As Statement 1 provides us with two possibilities for the value of x, i.e- (-1/2) and (1)
    Statement two provides us with the required data to fix on one particular value of x, which is (1).
