Question

Mark (a) if the question can be answered from statement I alone.
Mark (b) if question can be answered from statement II alone.
Mark (c) if question can be answered using both statements together but not by using either statement alone.
Mark (d) if the question cannot be answered by using both the statements.
Which is the greatest amongst a, b and c?
a + c = 2b
b= a+ d , c= a + 2d where d is a real number

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is D D

From I we can only infer that a, and c are in A.P.

From II we can infer a, b and c are in A.P but we don’t know if d is positive or negative. Thus we cannot find out the greatest number.

Option (d)
