Rank and order is an important point from the bank exam. In order and ranking questions, you have to find out the position of a person from left to right or from top to bottom.
Now, let's discuss each different case in Rank and Order.
1) Find out total no. of persons in a line
In this question, the below formula is used.
Total no of persons= Left position in the line + Right position in the line-1.
For Example:
A is 25th from the left and 32nd from the right, find out the total no of persons in the line.
Total no of persons = Left position in the line + Right position in the line-1.
Total no of persons = 25 + 32 -1 = 56
2) Find the total no of persons if there is a given a difference
Total no of persons = person's position from the given side or from the top or bottom + given difference
For Example:
A's position from the top is 17th and the persons behind A are 7. Find out total no of persons in a raw.
Total no of persons = person's position from the given side or from the top or bottom + given difference
Total no of persons = 17 + 7 = 24
3) When total no persons and position of two different persons given from the opposite. Find out no of persons between this two persons.
1) If Total no of persons> total of position of both opposite persons
Formula:
No of persons between two person's position = Total no of persons - total of both persons of opposite position
For example:
There are 58 persons in a row, in which A is 11th from the left and B is 22nd from the right side of the row. Find out no of people between A and B.
No of persons between two person's position = Total no of persons - total of both persons of opposite position
No of persons between two person's position =58 - (11+22)
2) If Total no of persons < total of position of both opposite persons
Formula:
No of persons between two person's position = Total of both persons of opposite position - total of all persons - 2
For example:
There are 50 persons in a row, in which A is 24th from the left and B is 30nd from the right side of the row. Find out no of people between A and B.
No of persons between two person's position =Total of both persons of opposite position - total of all persons - 2
No of persons between two person's position = (24+30) - 58
4) If persons interchange their positions in a row and the interchange position of one person given.
1) Total no of persons in a row = person position before change + person position after change - 1
For Example:
In a row A is 11st from the left and B is 18th from the right, after interchanging their positions A becomes 29th from the left. Find the total no of persons in a row.
Formula
Total no of persons in a row = person position before change + person position after the change - 1
Total no of persons in a row = 11 + 29 - 1
= 39
2) No of persons between A and B = person position after change - person position before the change - 1
Total no of persons in a row = 29 - 11 - 1
= 17
3) New position of the second person after interchange = Position of the second person from right side before interchanging + (Position of the first person from left side after interchanging – Position of A from left side before interchanging)
New position of the second person after interchange = 22+ (29-11)
= 18 + 18
= 36
