Question
Which of the following colour is filled in box D?
Answer the questions based on the information given below. Seven boxes viz. A, B, C, D, E, F and G are filled with different colours viz. Pink, Red, Green, White, Black, Yellow and Blue are kept one above another in a stack. The box kept at the lowermost position is numbered as 1 and the box kept at the topmost position is numbered as 7. Box F is kept four boxes above the box with yellow where the box with black is kept exactly in the middle between them. Only two boxes are kept between the box with black and box E which is not kept at the topmost position. As many boxes kept above box E as below the box with Blue which is kept two boxes away from box D. Box G with white is kept at an odd numbered position. Box C is kept immediately above the box with red and two boxes below box B. The box with pink is kept immediately below the box with green.Solution
Box F is kept four boxes above the box with yellow where the box with black is kept exactly in the middle between them. Only two boxes are kept between the box with black and box E which is not kept at the topmost position.
As many boxes kept above box E as below the box with Blue which is kept two boxes away from box D. Box G with white is kept at an odd numbered position.
Box C is kept immediately above the box with red and two boxes below box B. The box with pink is kept immediately below the box with green. Hence, cases 1 and 3 get eliminated.
