A B C D and E are sitting in a row. B is sitting between A and E. What is sitting in the middle?
1) A is sitting in the middle?
2) C is sitting on the extreme right.

Explanation

The question itself says that B is between A and E. Write it as:
`A gt B gt E` [ `.gt.` means .is to the left of. ]
Now, (1) implies:
`D gt A gt B`
And, (2) implies:
all `gt C`
Obviously, these can be combined into one single inequality:
`D gt A gt B gt E gt C`.
Hence, .B. is in the middle and the two statements together are sufficient to answer it. Hence, .C. is the answer.
