In Ordering and Ranking questions, rank or position of a person from right/left, top or bottom of a class or a row is determined. Also, a position or rank of the total number of people is to be calculated. Also, you may be asked to calculate the floor on which a person lives from the data given.

**Ordering and Ranking**

The Ordering and Ranking chapter is considered one of the important chapters in the reasoning section. In this article, we will discuss all the important tips, formula, and patterns of the questions that can be asked in the exam. Below are the forms of questions that can be asked from this chapter:

- The rank of a person from the right or left side
- Also, the total number of people based on the data given
- Maximum or minimum number of people in a row
- Also, the number of people between the two given person
- The rank of a person after interchanging their position
- Also, the total number of people on either side of the given person
- Also, ascending or descending order of people based on their categories like age, ranking, height, marks, etc.

**Concepts Regarding the Order and Ranking Topic**

**Case 1 **

Finding the total number of people when the ranks of one person are given

Total number of people = R1 + R2 – 1

Here R1 and R2 represent the rank of a person from both sides.

Ex: In a row, the position of Aman is 28th from the left side while the position from the right-hand side of the row is 33rd. How many total numbers of people are there in the row?

Total number of people = (Position of Aman from left side + position of Aman from the right side) – 1

= (28 + 33) – 1 = 59

Also, to find the position of a person from the opposite side when the rank of one side along with a total number of people is given.

= (Total number of people – position of the same from a given side) + 1

**Case 2 **

When in a row, the position of two people is given and their positions are interchanged. Also, after interchanging the position of the 1st person, it is given from the similar side as before the interchanging.

So, the new position of the 2nd person from a similar side before interchanging the = position of the 2nd person from the similar side before interchanging + (position of a 1st person after interchanging – position of the 1st person before interchanging from a similar side)

Total number of people = sum of positions of the people from both the sides – 1

Number of people between two people = Difference in the position of a person whose position is from a similar side after and before interchanging is given – 1

Ex. In a row of boys, Pramod us 14th from left and Kanu is 20th from the right. If both of them interchange the position than Pramod becomes 17th from left. Thus, what will be Kanu’s position from the right?

Total no. of girls = right end + left end – 1

= 17 + 20 – 1 = 36

Kanu’s position from right side = total girls – left end + 1

= 40 – 15 + 1 = 26

**Order and Ranking Questions**

A. Rashmi

B. Manisha

C. Sugandha

D. Priyanka

Answer:Â C. Sugandha

There are a number of errors on this page:

In example 2:

“You can see that each of the numbers is a square and that the sequence is a perfect square series. 1, 22, 32, 42 (=16). The alphabet that corresponds to 16 is P. ”

should read

“You can see that each of the numbers is a square and that the sequence is a perfect square series. 1, 2×2, 3×3, 4×4 (=16). The alphabet that corresponds to 16 is P. ”

(I suspect that the original text from which this was prepared used superscript but this has not been reflected in the online version, so use “2×2” or “2^2” which most people are familiar with from Excel)

In Circular Arrangement Series:

“These type of questions are similar to the ones we saw earlier. But there our numbering scheme would stop at 26 with X.”

should read

“These type of questions are similar to the ones we saw earlier. But there our numbering scheme would stop at 26 with Z.”

In example 3:

“Answer: The lesser the number of alphabets present, the greater the difficulty of the question. Here you see that V and A have a difference of 4 alphabets between them. Similarly, A and H have a difference of 6 alphabets between them if we follow the circular order of the alphabets. Thus the next alphabet will have to have a difference of 8 alphabets with H. This alphabet is Q. Thus the series is V, A, H, Q. Therefore the correct option is s) P.”

Similarly, A and H have a difference of 6 letters between them if we follow the circular order of the alphabets. Thus the next alphabet will have to have a difference of 8 letters with H. This letter is Q. Thus the series is V, A, H, Q. Therefore the correct option is d) P.”

In example 4:

“Answer: We will have to figure out the rule to every sequence. If you use the table, you will see that it becomes much more convenient to guess the rule. For example, in the first series, Q = 17; T = 20, X = 24; C = 29 [circular alphabet order]. Thus it forms a series under the rule. Similarly for the second option, F 6, P = 16, Z = 26 and J = 36. It also forms a correct sequence. Let us see the third one i.e. W = 23; U = 21; R = 18; and N = 14. So it is a wrong sequence. In place of N = 14, we should have had O.

That means the only series here that has a wrong term should be d). Let us check it. We have A = 1, L = 12, W = 23, H = 34.
