Six persons M, N, O, P, Q, and R were playing a game where they have to arrange six blocks of different shapes namely Circular, Hexagon, Rectangle, Square, Triangle, and Octagon one above the other in the form of a stack. Each person put up a different shape which was positioned from 1-6 where 1 is the bottom-most position.
Only one person kept a block between M and the person who kept the rectangle block. M who placed hexagon was just below Q. The rectangle block was kept at 3rd position. The circular block was kept by R just below M. The triangle was kept at an even position just above P, but not on the top. The difference in the position of the square block and the position at which N kept the block is 4.

Correct answer
Circular
Why this answer is correct
Six persons = M, N, O, P, Q & R
- The rectangle block was kept at 3rd position.

-
Only one person kept a block between M and the person who kept the rectangle block.
-
M who placed hexagon was just below Q.
Case 1:
| Position | Shape | Person |
|---|---|---|
| 6 | ||
| 5 | ||
| 4 | ||
| 3 | Rectangle | |
| 2 | Q | |
| 1 | Hexagon | M |
Case 2:
| Position | Shape | Person |
|---|---|---|
| 6 | Q | |
| 5 | Hexagon | M |
| 4 | ||
| 3 | Rectangle | |
| 2 | ||
| 1 |
- The circular block was kept by R just below M.
(So,case 1 is invalid. Move ahead with case 2.)
| Position | Shape | Person |
|---|---|---|
| 6 | Q | |
| 5 | Hexagon | M |
| 4 | Circular | R |
| 3 | Rectangle | |

- The triangle was kept at an even position just after P, but not on the top.
| Position | Shape | Person |
|---|---|---|
| 6 | Q | |
| 5 | Hexagon | M |
| 4 | Circular | R |
| 3 | Rectangle | |
| 2 | Triangle | |
| 1 | P |
- The difference in the position of the square block and the position at which N kept the block is 4.
| Position | Shape | Person |
|---|---|---|
| 6 | Square | Q |
| 5 | Hexagon | M |
| 4 | Circular | R |
| 3 | Rectangle | O |
| 2 | Triangle | N |
| 1 | Octagon | P |
Thus, R kept the circular block.
