In a row of five buildings - A, B, C, D and E, which building is in the middle?
(I) Buildings D and B are at the two extreme ends of the row.
(II) Building E is to the right of building C.
Answer & explanation
Correct answer: option 3
From Statement I,
Two cases are possible:-
D, _, _, _, B
or
B, _, _, _, D
Nothing can be said about the building in the middle.
From Statement II,
Four cases are possible:-
C, E, _, _, _
or
_, C, E, _, _
Or
_, _, C, E, _
Or
_, _, _, C, E
Nothing is certain about the middle building, as in different cases it'll be different.
Hence, Option D is correct, as the data even in both statements I and II together are not sufficient to answer the question
