Tricks for Solving IBPS RRB Ordering and Ranking Questions

Let us now look at some of the common types of IBPS RRB ordering and ranking questions and see the tricks you can use to solve them quickly and efficiently.

Finding the Total Number of Persons Sitting in a Column

Question: Sachin is 18th from left and 19th from right in a row. How many people are sitting in the row

Solution: To solve such problems, you need to use the following formula:

Total= (r1 + r2) – 1

where r1 is the position of the person on one side and r2 is the position of the person from the other side.

In this case, r1 is 18 and r2 is 19. So we have :

Total number of persons in the row= (18+19)-1=36.

Answer: 36

Question: In a class, Sohan’s rank is 9th from the left and Sohail rank is 7th from the right. If 6 students are sitting between them then calculate the total number of students in the class.

Solution: In such cases, we have to use the following formula

Total = (r1 + r2) + Number of middle persons.

Applying the above formula to the question we have,

Total=9+7+6=22

Question: Priya is 24th from the right in a row of 40 girls. What is her position from the left end?

Solution: To find the rank from any one side, you should use the following formula

Required rank=(Total + 1) – Given rank 

So, we have

Required rank = (40+1) -24= 41-24=17

Answer: 17

Finding the Number of Persons Sitting Between Two Persons

Question: In a class of 120 students, Vivek is 44th from the left and Yash is 46th from the right. Find the total number of students sitting between them?

Solution: The first thing that you need to find is whether the people are overlapping or not. To find that, you just need to add the two ranks and see whether the number is less than the total number.

In this case,

44+46=90, which is less than 120.

There is no overlapping, so we are going to use the following formula.

Total – (Rank from left + Rank from Right).

So, we have

120 -90= 30

Answer: 30 students are sitting beside them.

In case of overlapping i.e. the total number is less than the sum of the ranks, then you need to use the following formula

(Rank from left + Rank from right)–(Total + 2).

List of Important Formulas

  • If you are asked to find the number of people in a row and the ranks of two persons are given,

Total= (r1 + r2) – 1

  • If you are asked to find the number of people in a row and the number of people sitting in the middle is given

Total = (r1 + r2) + Number of middle persons.

  • If you are asked to find the rank of a person from left or right and the total number of persons, as well as the rank of the person from the other side, is given

Required rank=(Total + 1) – Given rank 

  • Number of persons sitting between two persons
    • for simple – Total – (Rank from left + Rank from Right).
    • for overlapping – (Rank from left + Rank from right)–(Total + 2)
