Read the given information carefully and answer the related questions:

Six boxes - A, B, C, D, E and F are placed one above another. These boxes are of different types – Jute, Steel, Iron, Wood, Leather, Brass. All the information is not necessarily in the same order. Box D is placed three places above leather box. Same number of boxes are placed above box D and below steel box. Box B is placed just below box F and juts above wood box. Box A is placed two places below iron box. More than one box is placed below box C which is placed below brass box.

Box F is of which type?

The correct answer is Iron.

Step-by-Step Explanation and Derivation:

Let us number the 6 positions from top to bottom as follows:
Position 6 (Top)
Position 5
Position 4
Position 3
Position 2
Position 1 (Bottom)

Step 1: Determine the positions of Box D, Leather box, and Steel box.
1. "Box D is placed three places above leather box."
This means Position of Box D - Position of Leather box = 3.
2. "Same number of boxes are placed above box D and below steel box."
If Box D is at the top (Position 6), 0 boxes are above Box D, which implies 0 boxes are below the Steel box, placing the Steel box at Position 1 (Bottom).
Since Box D is 3 places above the Leather box, the Leather box must be at Position 3 (6 - 3 = 3).

Step 2: Determine the positions of F, B, and Wood box.
1. "Box B is placed just below box F and just above wood box."
This creates a contiguous vertical stack of three items: Box F → Box B → Wood box.
2. Since Position 3 is already identified as the Leather box, Box B (which is at Position 3) must be the Leather box.
Therefore:
- Box F is at Position 4.
- Box B is at Position 3 (Leather box).
- Box A/Wood box is at Position 2.

Step 3: Identify the type of Box F using the Iron box clue.
1. "Box A is placed two places below iron box."
Since Box A is at Position 2, the Iron box must be at Position 4 (2 + 2 = 4).
2. Since Position 4 is occupied by Box F, Box F must be the Iron box.

Step 4: Verify the complete arrangement.
1. Clue: "More than one box is placed below box C which is placed below brass box."
- Box C must be at Position 5 (so that 4 boxes are below it, which is more than one).
- Box D at Position 6 is the Brass box.
- Box E is at Position 1 (Steel box).
- Box C is at Position 5 (Jute box).

Final Arrangement (Top to Bottom):
Position 6: Box D (Brass)
Position 5: Box C (Jute)
Position 4: Box F (Iron)
Position 3: Box B (Leather)
Position 2: Box A (Wood)
Position 1: Box E (Steel)

Hence, Box F is of Iron type.
