Circular Arrangement Facing Centre and Outside


 
 
Concept Explanation
 

Circular Arrangement Facing Centre and Outside

Seating Arrangement:  These type of questions are the most common type in most of the competitive examinations where are reasoning of the candidate is to be analysed. These concepts involve the arrangement of objects/ people in various ways. Generally one problem is followed by five to six questions so it is always advantageous to attempt the seating arrangement questions in the examination, because by solving one problem we are fetching more marks than by solving other single questions.

Circular Arrangement Facing Centre And Outside: In facing away from the center that is outside, left means anti-clockwise while right means clockwise direction.  In circular arrangement  facing towards the centre means right means anti-clockwise Direction and left means clockwise Direction. As both the concepts are to be applied to the same question, we will draw a diagram depicting the position of the objects or people. When the question arises where both type of sitting is provided, we will follow the rulers of both the directions and draw as many alternatives as available Later, according to the conditions provided the alternatives will get eliminated & only I valid diagram will remain. We will then analyse the position of the various objects or the people and will then answer the questions.

Illustration: Study the following information to answer the given questions :

V, U, T are seated in a circle facing to the centre. A, B, C, are also seated in same circle but two of them are not facing centre (opposite of the centre). V is second to the left of C. U is second to the right of A. B is third to the left of T. C is second to the right of T. A is next to V..

What is position of A with respect to B ?

A.  2nd to the left                 B. 3rd to the right                 C. 2nd to the right                    D. 3rd to the left    

Answer: A

Solution: When the question arises where both type of sitting is provided, we will follow the rulers of both the directions and draw as many alternatives as available Later, according to the conditions provided the alternatives will get eliminated & only I valid diagram will remain.

Given : - V, U, T - Facing centre A, B, C, - direction unknown

(a)  Since C's direction is not known, it can face inward / outward. So we will form 2 possibilities.

Fig. I

Fig. II

(b)  Also it is given then C is second to the right of T. So the Fig I gets eliminated as T can't be placed there.After placing T the Fig. II figure will be as shown in Fig. III

Fig. III

(c)  Now it is given U is second to right of A. Two possibilities.

Fig. IV

Fig. V

(d)  B is third to right of T. So B cannot be placed in Fig. IV. Hence Fig IV is eliminated and after placing B the Fig. V figure will be as shown in Fig. VI. Moreover only two are facing outwards so U will face inwards. Hence the final diagram will be Fig. VII

Fig VI

Fig. VII

 From the diagram it is clear that counting from B in anticlockwise direct, A is second to the left of B.Hence A is the correct option.

Question : 2
Read the comprehension carefully to answer the given question.
 
Eight persons – A, B, C, D, E, F, G and H are sitting around a circular table, but not necessarily in the same order. Four of them are facing inside while rests of them are facing outside.
 
C is not adjacent to A, who is facing same direction as B. Two persons are sitting between E and G, who are facing different directions. B is sitting fourth to the left of E, who faces centre. E is sitting second to the right of C. Only one person is sitting between A and H, who are facing different directions. F is to the immediate left of H, who is facing same direction as E. D and F are facing same directions.
 
Who among the following faces the same direction?
Right Option : D

Question : 3
Directions: Study the following information carefully and answer the given questions.

Eight persons – Barkha, Rajdeep, Arnab, Kashyap, Menon, Razdan, Mehta and Ravish - are sitting around a circle at equal distance between two persons but not necessarily in the same order. Some of them are facing towards the centre while some others are facing outside the centre. Ravish is sitting 3rd to the left of Mehta. Both Mehta and Ravish are facing towards the outside. Kashyap is not an immediate neighbour of Mehta or Ravish. Razdan faces the just opposite direction of Kashyap. (It implies that if Kashyap is facing towards the centre, Razdan would face outside the centre).  Razdan is sitting 2nd to the left of Kashyap.  Both the immediate neighbours of Arnab face just opposite direction of Arnab. Barkha is an immediate neighbour of Mehta. Both the immediate neighbour of Kashyap face just opposite direction of Kashyap. Barkha faces towards the centre and she is an immediate neighbour of both Mehta and Menon. Menon faces towards the centre.
