Q. Let α and β be the two distinct roots of the quadratic equation ax2 + bx + c = 0. Both α and β are two digit integers with same unit digit.
Statements:
A. Determinant is not a multiple of 100.
B. Unit digit of (α+β)/2 is not ZERO.
Mark (1) if the question can be answered by using the statement A alone but not by using the statement B alone.
Mark (2) if the question can be answered by using the statement B alone but not by using the statement A alone.
Mark (3) if the question can be answered by using either of the statements alone.
Mark (4) if the question can be answered by using both the statements together but not by either of the statements alone.
Mark (5) if the question cannot be answered on the basis of the two statements.
Please use the thread as judiciously as you can.
Try to stick to the purpose of the thread.

If statement 1 is false or statement 2 is false we get the answer as '0'
