Ranking Test

The process of determining the position or place of a person or a thing on the basis of comparison or relative position of other person or thing is called ranking. There are two types of questions based on ranking test which in as follows.

Ranking Test : In this type of questions, a set of information pertaining to persons, objects or some other entities along with their qualities, which can be compared is provided. Candidates are required to arrange the given entities in either ascending or descending order on the basis of relative quality. At first look, such questions appear to be very simple but sometimes these are made tricky by infusing intricacies and complicated data.

However, one can organise the given data quickly and easily by comprehending the given information in systemation manner. Sometimes, the given information may seem to be insufficient but a cogent analysis of the same reveals useful clues and the problem turns to be very simple. You may also find some superfluous statement which can confuse to you. You can recognise such statements in no time, if you have gained command over such types of questions.

Sometimes you are required to ascertain only the rank of a person either from top or bottom in a class or a group of persons. In determining the rank, the information about total number of persons in the class or a group is a pre-requisite otherwise you cannot determine the rank.

Sometimes the rank of a person from either end is given and you are required to calculate the total number of persons.

Let there be n persons who qualified in a certain event. A particular girl Priya is one of them whose rank from the top i.e., Top rank $(T_r)$ is 16th and his rank from the other side i.e., Bottom rank $(B_r)$ is 2nd. Then, total number of girls (n) who qualified, is

$Rightarrow$ $n=T_r+B_r-1 ;;; Rightarrow ;;; n=26+16-1=41$

Example 1 : - In a row of boys, Ram is seventh from the left and Shyam is twelfth from the right. If they interchange their positions, Ram becomes twenty-second from the left. How many boys are there in a row ?

(a) 49 (b) 31 (c) 33 (d) Data inadequate

Solution : - (c) Ram's new position is 22nd from left. But is the same as Shyam's earlier position, which is 12th from right.

$Rightarrow$ The number of persons in a row $=T_r +B_r-1=(22 + 12-1)=33$

Example 2 : - In a class, Ajit ranks 11th from the top and 27th from the bottom. If in the same class Anuja ranks 14th from the top, how many children below Anuja, in the class ?

(a) 23 (b) 30 (c) 24 (d) 29

Solution : - To Finding the total number in a sequence/order. Values required to find the total number:

(1) Rank of a person from one side.

(2) Rank of same person from another side.

Formula to find total number is:

Total number Rank of the person from left end + Rank of a person from right end -1

Total number of students in the class = 10 + 1 + 26 = 37

Anuja's rank from top = 14th

Therefore, the number of students, who are below Anuja in the class = 37 - 14 = 23
