Question from UPSC Prelims 2021 CSAT Paper
Explanation : From Statement-1 alone we know that one of A or D is the heaviest among A, B, E and F. However we do not have any information about C.
From Statement-2 alone we know that C is heavier than A but we do not have any information about how C compares to B,E,F or D.
Combining both statements we can conclude that C is the heaviest among A,B,C,D and E because from statement 1 we know that either A or D are the heaviest among A,B,E,F and from statement 2 we know that C is heavier than both A and D.
So both Statement-1 and Statement-2 are required to answer the Question.
