Consider two Statements and a Question:

Statement-1: Each of A and D is heavier than each of B, E and F, but none of them is the heaviest.
Statement-2: A is heavier than D, but is lighter than C.

Who is the heaviest among A, B, C, D and E?

Which one of the following is correct in respect of the Statements and the Question?

Statement 1 mentions A & D are not the heaviest (in the entire set). But among a smaller set, any of the two could be heavier than other and all others.

A > B, E & F D > B, E & F

But relationship between A & D is unknown, ie anyone can be heavier. so, using statement 1 alone we cannot determine the heaviest item

Statement 2 gives C > A > D

So, using statement 2 alone also we cannot determine the heaviest item.

But, using both statements we can solve easily as the unknown relationship between A & D gets defined along with the missing letter C, so we have C > A > D > B, E & F. So, C is heaviest.

So, both options (c) and (d) are correct.
