Eight boxes namely -A, B, C, D, E, F, G and H are kept one above another not necessarily in the same order. Box C is kept third from bottom at a gap of two from box D, which is kept adjacent to box B and box A is kept at a gap of one from B. Which box is kept immediate above box E?

I. Box G is kept at a gap of two from box A and Box H is neither kept at bottom nor adjacent of C. Box G is kept at a gap of two from box F.

II. Box F is kept at a gap of two from box G, which is kept adjacent of box C. Box H is kept immediate neighbor of box A.

A If the data in Statement I alone is sufficient to answer the question, while the data in Statement II alone is not sufficient to answer the question. Correct Answer Incorrect Answer
B If the data in Statement II alone is sufficient to answer the question, while the data in Statement I alone is not sufficient to answer the question. Correct Answer Incorrect Answer
C If the data either in Statement I alone or in Statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
D If the data in both the Statements I and II together are not sufficient to answer the question. Correct Answer Incorrect Answer
E If the data in both the Statements I and II together are necessary to answer the question. Correct Answer Incorrect Answer

Solution

We have: Box C is kept third from bottom at a gap of two from box D, which is kept adjacent to box B that means box D is kept third from top and we have two different case for box B, in case (1) box B is kept immediate above box D and in case (2) box B is kept immediate below box D.  Box A is kept at a gap of one from box B, which means in case (1) A is kept immediate below D and in case (2) box A is kept immediately above box D. Based on above given information we get: From I: We have: Box H is neither kept at bottom nor immediate neighbor of C, which means box H is kept at top. Box G is kept at a gap of two from box A, which means in case (1) G is kept immediate above box C and in case (2) box G is kept immediate above box C.  Box G is kept at a gap of two from box F, which means case (1) is not valid and in case (2) box F is kept at bottom. Based on above given information we get final arrangement as follow: Thus, box C is kept immediate above box E. Hence, statement I alone is sufficient. From II: We have:  Box H is kept immediate neighbor of box A, which means in case (1) box H is kept immediately below box A and in case (2) the box H is kept immediately above box A. Box F is kept at a gap of two from box G, which is kept immediate neighbor of box C, that means case (1) is not valid and in case (2) box G is kept immediate above box C. Based on above given information we get final arrangement as follow: Thus, box C is kept immediate above box E. Hence, statement II alone is sufficient.
