Answer 1

Correct Answer - Option 1 : Pink

In the given question,

Going step by step,

Four boxes between Pink and Red box

Case 1	Case 2	Case 3
Pink
	Pink
		Pink/Red
Red
	Red
		Pink/Red

 

In case 1, we know that White is above red so red cannot be at the top. 

Similarly, in case 2 White is above red but cannot be at the top, therefore, red cannot be second from the top.

There are two boxes between Red and Green.

Case 1	Case 2	Case 3
Pink
	Pink
Green		Pink/Red
	Green
		Green
Red		Green
	Red
		Pink/Red

 

Three boxes are kept between orange and green box

Case 1	Case 2	Case 3
Pink		Orange
	Pink	Orange
Green		Pink/Red
	Green
		Green
Red		Green
Orange	Red
	Orange	Pink/Red

 

Two boxes are kept between orange and blue box

Case 1	Case 2	Case 3
Pink		Orange
	Pink	Orange
Green		Pink/Red
Blue	Green	Blue
	Blue	Green/Blue
Red		Green
Orange	Red
	Orange	Pink/Red

 

Only one box is kept between Blue and Black box, looking at the ambiguity of case 3 we can remove it.

Case 1	Case 2
Pink
Black	Pink
Green	Black
Blue	Green
	Blue
Red
Orange	Red
	Orange

 

There are two boxes between the white and yellow box and white box is placed above red box

Case 1	Case 2
Pink
Black	Pink
Green	Black
Blue	Green
White	Blue
Red
Orange	Red
Yellow	Orange

 

Since it was only possible in Case 1, Case 1 is the correct sequence.

Case 1

Pink

Black

Green

Blue

White

Red

Orange

Yellow

 

Therefore, we can find that Pink is at the top.

Hence, Option 1 is the correct answer.
