Mensa IQ Test Mensa IQ Ranking, Ordering, and Seating Arrangements

Question 1

Five students — A, B, C, D, E — sit in a row. A sits to the right of B, C sits to the left of D, and E sits between A and C. Who sits in the middle?

Accepted Answer

E

Answer

From the clues: B…A (B left of A), C…D (C left of D), E between A and C. A valid arrangement is B, A, E, C, D — placing E in position 3, the middle seat.

Question 2

In a class of 30, Ravi ranks 8th from the top. What is his rank from the bottom?

Accepted Answer

23

Answer

Rank from bottom = Total − Rank from top + 1 = 30 − 8 + 1 = 23.

Question 3

Six people sit around a circular table. If A is directly opposite B and C is immediately to A's left, which of the following must be true?

Accepted Answer

C is immediately to B's right

Answer

In a circular arrangement A and B are opposite; C is immediately left of A. When looking from the centre, 'immediately left of A' is immediately right of B (the person directly facing A), so C is immediately to B's right.

Question 4

P, Q, R, S, T stand in a queue. P is ahead of Q. R is behind S. T is between Q and R. Who is at the front of the queue?

Accepted Answer

S

Answer

Combining constraints: S…R (S ahead of R), P…Q (P ahead of Q), Q…T…R (T between Q and R). A valid order is S, P, Q, T, R — placing S at the front.

Question 5

In a group of 50 students, Anita is 20th from the top. What is her rank if 5 new students, all better than her, join the group?

Accepted Answer

25th

Answer

5 students who rank higher than Anita join; each pushes her one place down. Her new rank = 20 + 5 = 25th from the top.
