If we arrange all the boxes in alphabetical order from top to bottom, then which among the following box will be of grey colour? Study the following information carefully and answer the questions given below:

Six paint boxes are kept one above another in the form of the stack. Each box has different colours paint- Pink, Blue, Red, White, Yellow and Grey but not in same order as given.

Yellow coloured box is kept three boxes above box B. Box D is kept adjacent to box B. As many boxes are kept above box D as below red coloured box. Box E is kept immediately below red coloured box. Box B is not red in colour. More than one box is kept between box E and the grey coloured box. Box D is kept above grey coloured box. Box A is kept above the white coloured box but below box C. Box B is not kept below white coloured box. More than one box is kept between box F and blue coloured box. Pink coloured box doesn’t keep adjacent to blue coloured box.

The correct option is Box F.

Step-by-Step Explanation:

1. Determine the top-to-bottom stack arrangement:

Let the positions of the boxes in the stack be numbered from 1 (Top) to 6 (Bottom).

• Yellow is kept 3 boxes above Box B, so if Yellow is at Position 1, Box B must be at Position 4.
• Box D is adjacent to Box B, placing Box D at Position 5.
• There are 4 boxes above Box D (Positions 1 to 4). Therefore, there must be 4 boxes below the Red box, placing the Red box at Position 2.
• Box E is immediately below the Red box, placing Box E at Position 3.
• Box D (Position 5) is above the Grey box, placing the Grey box at Position 6.
• Box C is above Box A, which is above the White box. Placing Box C at Position 1, Box A at Position 2, and Box F at Position 6.
• Since Blue has more than one box between it and Box F (Position 6), Blue must be at Position 3 (Box E).
• Pink cannot be adjacent to Blue (Position 3), so Box B (Position 4) is White and Box D (Position 5) is Pink.

Final Stack Arrangement (Top to Bottom):

1. Box C — Yellow
2. Box A — Red
3. Box E — Blue
4. Box B — White
5. Box D — Pink
6. Box F — Grey

2. Arrange boxes in alphabetical order from top to bottom:

1. Box A (Red)
2. Box B (White)
3. Box C (Yellow)
4. Box D (Pink)
5. Box E (Blue)
6. Box F (Grey)

Therefore, Box F is of grey colour.
