IBPS has conducted the Prelims Exam for the post of Probationary Officers successfully across the country in the month of October 2018. The exam was conducted in four different slots. This article on IBPS PO Prelims 2018 : Memory Based Sitting Arrangement Puzzle consists of Circular Arrangement and Linear Arrangement questions.

### Circular Arrangement

Directions :Six friends A, B, C, D, E, F traveling to six different cities Delhi, Pune, Kolkata, Mumbai, Banglore and Chennai. They are sitting around a circular table facing towards the center.

There are two people traveling between the one who travels to Kolkata and A. There is only one person traveling between A and the one who travels to Pune (either to the left or Right of A). F sits to the immediate left of the one travelling to Pune. F doesn't travels to Kolkata. The person who is traveling to Mumbai sits to the immediate right of the one traveling to Kolkata. There are two persons sitting between the those traveling to Mumbai and Delhi. C sits to the immediate left of the one who travels to Mumbai. A, who is traveling to Hyderabad sits to the immediate right of D. E don’t travel to Pune.

Solution :

While solving any puzzle it's very  important to choose the right statements first, inorder to solve the puzzle as early as possible. But usually, we mess it up even with the simple puzzles during the examination, and as a result end up wasting a lot of our quality time.

Therefore inorder to avoid the puzzle, we should first start with some Direct statements in which the given information is easier to work with. So let's start arranging the data given in this puzzle having two variables. We will try to explain the solution step by step.

In this Circular Arrangement question, the first statement says that There are two people traveling between Kolkata and A. So we will first draw a circle and arrange this data, accordingly. Next statement says that There is only one person traveling between A and the one who travels to Pune (either to the left or Right of A. Now we need to make one more circle and make it a possibillity case having two parts, as shown below.
 case (i)
 case (ii)

After this, the third and the fourth statement says that F sits to the immediate left of the one travelling to Pune and F doesn't travels to Kolkata. These statements make it clear that only  case (i) follows and we should cancel the case (ii) as it's redundant now.

Furthermore, we will arrange the next given statements saying The person traveling to Mumbai sits to the immediate right of the one traveling to Kolkata and then the statement which says that There are two persons sitting between the those traveling to Mumbai and Delhi. This statement here makes no two different possibilities as only one case is possible.

Now we will arrange the last two statements - C sits to the immediate left of the one who travels to Mumbai. A, who is traveling to Hyderabad sits to the immediate right of D. E don’t travel to Pune. And our Final Arrangement will look like as shown below.
 Final Circular Arrangement

Time taken to solve this puzzle is around 2 to 3 minutes. Make sure to practice pretty well and arrange it within this time period only, so that you can save some time for the other questions.

### Linear Arrangement

Directions : Twelve persons are sitting in two parallel lines in such a way that there are six persons in each row at equidistant. A, B, C, D, E and F are sitting in row-1 and they face towards south. P, Q, R, S, T and V are sitting in row-2 and they face towards north. One person sitting on one row faces the other person of the other row.
P, who sits at one of the ends of the row, is second to the right of T. A does not face P or T. A is third to the left of F. There are two persons between Q and V. There is only one person who sits between C and D. C and D do not face P. B is neighbour of C. S, who is not facing D, is not the neighbor of Q.

Solution
Solving Linear Arrangements questions is easier than circular arrangements questions, if you pick up or choose the right statements smartly.

Let's start solving this puzzle, we will be explaining the step by step process of arranging these data in a short span of time. This Linear Arrangement question consists of only one variable, so it will be easier to deal with as compared to other sitting arrangement questions.
Quickly, first make two parallel lines representing row 1 & row 2, and starting with the statement that P, who is sitting at one of the ends of the row, is second to the right of T. In this statement, only one case is possible, since both P and T are facing north & if P is sitting second to the right of T, then ultimately P cannot be made sit at the leftmost end of the line.

Next the statements, A does not face P or T. A is third to the left of F, again makes only one possible case. Now the statement which says 'There are two persons between Q and V', makes it clear that there's a possibility case as illustrated in the diagram below.
 case (i)

 case (ii)
Afterwards, the statements here are connected which says There is only one person between C and D. C and D do not face P. B is neighbour of C. As these instructions are direct, we will try to arrange them as written above.

Lastly, the statement - S, who does not face D, is not the neighbor of Q, makes it clear that only case (ii) is possible, so we now eliminate the case (i) and proceed implementing the remaining data. The final arrangement will look similar to the below shown figure.
 Final Linear Arrangement
Time taken to solve this Linear Arrangement question is again around 2 to 3 minutes, as here lies a possibility case too, the same way how it was in Q.1 of circular arrangements. Make sure to practice well and try to solve it within the same time period as mentioned.

Our final words would be that,solving puzzles is more about Smart Work and not just about Hard Work. If you solve it wisely,then it will become a piece of cake walk for you.
