Directions: Each of the questions below consists of a question and two Statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question:
In a society there are five houses - A, B, C, D and E, built in a row, which house is in the middle?
Statement I: Houses D and B are at the two extreme ends of the row.
Statement II: House, E is to the right of house C.
Correct Answer : d ) Neither I nor IIExplanation :
(i) Houses D and B are at the two extreme ends of the row.
From the above statement, we get two possible orders: (i) D, -, -, -, B or (ii) B, -, -, -, D
This statement alone cannot conclude the house in the middle of the row.
(ii) House, E is to the right of building C.
The house in the middle of the row cannot be determined using this statement.
Combining statement, I and statement II:
Combining the above two, we get two possible orders: D, C, E, A, B or D, A, C, E, B. Thus, either E or C is in the middle.
Therefore, Neither I nor II is sufficient to answer the question.
Hence, (d) is the correct answer.
