Question: Each question is followed by two statements A and B. Answer each question using the following instructions.
Mark (1) if the question can be answered by using statement A alone but not by using statement B alone.
Mark (2) if the question can be answered by using statement B alone but not by using statement A alone.
Mark (3) if the question can be answered by using both the statements together but not by using either of the statements alone.
Mark (4) if the question cannot be answered on the basis of the two statements.
Consider integers x, y and z. What is the minimum possible value of x2 + y2 + z2 ?
A. x + y + z = 89
B. Among x, y, z two are equal.
But 89/3 is a non-integer. ∴ We consider integer values of x, y, z which are as close as possible to 89/3.
Hence, option (a).
