Data Sufficiency Seating Arrangement

The Data Sufficiency questions do not require the student to find the exact answer. Infact the only thing that a student is required to determine is that whether the statements provided in the question contain enough information for answering it.

You need to remember the steps involved in solving a particular Data Sufficiency question and follow them in this particular order: Check A (i.e. the first statement), then Check B (i.e. the second statement) and lastly, if required, combine the two statements to get the answer.

Data Sufficiency Involving Seating Arrangements:

The questions on seating arrangement with data sufficiency are regular feature of almost every competitive examination. In these questions, you have to arrange a group of persons fulfilling certain conditions. Here we can classify these problems into 4 types:

Linear Arrangement: Here the arrangement of the persons is linear i.e. you have to arrange them in a line.

Double row arrangement: In these questions, there will be two groups of persons. The persons in these rows normally face each other.

Circular arrangement: In the circular seating arrangement questions, you have to arrange the persons around a circular table etc. fulfilling certain conditions.

Rectangular arrangement: In the rectangular seating arrangement questions, you have to arrange the persons around a circular table etc

Direction : - Each of the questions below consists of a questionand two statements numbered I and II given below it. You have to decide whetherthe data provided in the statement are sufficient to answer the question.Read both the statements and give answer(a) if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question;(b) if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question;(c) if the data either in statement I alone or in statement II alone are sufficient to answer the question;(d) if the data given in both statements I and II together are not sufficient to answer the question; and(e) if the data in both statements I and II together are necessary to answer the question.

Question : - A, B, C, D and E are seated around a circular table facing at the centre. Who is to the immediate right of B ?

I. D is in between A and E.

II. C is in between B and E.

Answer (d) : - From I, we have : .

From II, we have :

Combining the above two, we have :
