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)
