Verbal Reasoning - Data Sufficiency - Discussion
In each of the following problems, there is one question and three statements I, II and III given below the question. You have to decide whether the data given in the statements is sufficient to answer the question. Read all the statements carefully and find which of the statements is/are sufficient to answer the given question. Choose the correct alternative in each question.
Question: Five persons - A, B, C, D and E are sitting in a row. Who is sitting in the middle?
- B is between E and C.
- B is to the right of E.
- D is between A and E.
I want to say that B is between E & C doesn't mean EBC or CBE it can also be EADBC or EDBAC or EBADC or many more such combinations but why only take EBC or CBE?
Anyone, please explain to me.
The combination can be.
E B C or C B E.
By using 3 (without seeing 2).
We can say that it is.
A D E B C or C B E D A.
FROM USING 1 AND 2 WE CAN BE SURE THAT 'E' IS IN MIDDLE.
So, option C is correct.
From II, the order is : E, B.
From III, the order is : A, D, E (or the order can be E, D, A as well).
Combining I and III, we get two possible orders as:A, D, E, B, C and C, B, E, A, D.
Clearly, in both, E is seated in the middle, irrespective of whether E is seated to the right or left of B.
So the correct option should be "option [C]".
So the answer should be [C]ONLY I AND III.
