SSC CHSL Topic Wise Study Material – General Intelligence – Order and Sequence
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. In ranking test, relative position or ranking of different groups of persons/objects are given. Students are required to establish the ranking or position of other individual in the same group with respected to one another.
Two types of questions covered in this chapter are as follows
1. Sequential order of arrangement
2. Position test
1. Sequential Order of Arrangement
This type involves determining the sequential order of two or more persons/objects based on the comparison of parameters such as age, height, mark, salary, weight etc. Questions based on ranking are generally given with a set of information in jumbled form and based on that it is required to systematically arrange the given information and answer the questions asked.
Example In a group of five districts, Akbarpur is smaller than Fatehpur, Dhanbad is bigger than Palamu and Bara Banki is bigger than Fatehpur but not as big as Palamu. Which district is the biggest? ssc (10+2) 2011
(c) Dhanbad > Palamu > Bara Banki > Fatehpur > Akbarpur
Hence, Dhanbad district is biggest amongst them.
2. Position Test
In this type, the rank or position of persons/objects from either of the two ends of a row/queue is given and it is required to determine the total number of persons in the group or the position of the persons from left or right side in a row/queue.
Different types of position tests will give you a better idea
(i) Rank of a Person/Object from Top or Bottom from Left or Right
In this type of questions, it is asked to determine the rank or position of a person/object in a group of persons/objects either from the left (or right) or from the top (or bottom) depending upon the arrangement.
The position or rank can be calculated with the help of following formulae
• Position (or rank) from the left end (or top) = (Total number of persons/students – Rank from the right end (or bottom) + 1
• Position (or rank) from the right end (or bottom)=(Total number of persons./students – Rank from the left end (or top) + 1
Example In class of 45 students rank of Ayush is 15 from top, then rank of Ayush from bottom is
(ii) Total Number of Objects/Persons in Queue
In this type of questions, it is asked to Calculate the total number of persons when the rank of a person from both the ends is given.
Following formula is helpful in the calculation of total number of objects/persons in a queue
Total number of persons in a row or queue = (Position (or rank) of a person from the left end (or top or front) + Position (or rank) of the person from the right end (or bottom or last) -1
Example In a queue, Soham is 10th from left and 28th from right. How many people in the queue?
1.P, Q, R, S and T are sitting together. T is at one extreme end. P is the neighbour of T and is third to the left of Q. Who is fourth to the right of T? SSC (10 + 2) 2017
2.Barun is taller than Sanjay. Bipul is taller than Barun. Krishna is also not as tall as Bipul, but is taller than Barun. Who is the tallest? SSC (10+2) 2013
(b) The information given in the question may be interpreted systematically as follow
Bipul > Krishna > Barun > Sanjay
So, Bipul is the tallest.
3.Sunita is the 11th from either end of a row of girls. How many girls are there in that row? SSC (10+2) 2013
(c) The total number of girls = 11 + 11-1 = 22-1
4.At a birthday party, 5 friends are sitting in a row. ‘M’ is to the left of ‘O’ and to the right of ‘P’. ‘S’ is sitting to the right of T’, but to the left of ‘P’. Who is sitting in the middle? SSC (10+2) 2013
5.In a row of letters, a letter is 5th from left end and 12th from the right end. How many letters are there in a row? SSC (10+2) 2013
(b) Number of letters in the row = 5 + 12-1=16
6.Lakshmi is elder than Meenu. Leela is elder than Meenu but younger than Lakshmi. Latha is younger than both Meenu and Hari but Hari is younger than Meenu. Who is the youngest? SSC (10+2) 2013
(d) According to the question.
Lakshmi > Meenu
Lakshmi > Leela > Meenu
Meenu > Hari > Latha
Lakshmi > Leela > Meenu
> Hari > Latha
Hence, Latha is the youngest.
