Five persons A, B, C, D and E are sitting in a row facing you such that D is on the left of C and B is on the right of E. A is on the right of C and B is on the left of D. If E occupies a corner position, then who is sitting in the centre ?
Answer: D
D is on the left of C i.e. C, D.
B is on the right of E i.e. B, E.
A is on the right of C i.e. A, C.
B is on the right of D i.e. D, B.
From the above statements, the correct order is : A, C, D, B, E.
Clearly, D is sitting in the centre.

Compare the knowledge of persons X, Y, Z, A, B and C in relation to each other : 1. X knows more than A. 2. Y knows as much as B. 3. Z knows less than C. 4. A knows more than Y. The best knowledgeable person amongst all is:
Answer: A
Correct answer: X
The statements give one chain: A knows more than Y, Y knows as much as B, and X knows more than A, so \( X > A > Y = B \). The remaining clue places C above Z but connects that pair to no one else, so C cannot be ranked against X at all. Of the four names offered, X is the only one standing above everyone it can be compared with.

Every novel has a drama next to it, every story-book has a comic next to it and there is no story-book next to novel.
If there be a novel at the top and the number of books be 40, the order of the books in the pile is :
Answer: B
Correct answer: ndsc
Test the order novel, drama, story, comic repeated through the pile. Each novel has a drama immediately below it, satisfying the first rule. Each story-book has a comic immediately below it, satisfying the second. And no story-book touches a novel, since the drama above it and the comic below it keep them apart - the comic separating each story-book from the novel that begins the next group of four.
