Whenever you are solving number ranking you have to know mainly two types of symbols. One is greater than symbol (>) and other is less than symbol (<). Also, to solve these questions you have to only know three things greater than a symbol, smaller than a symbol, and equal to symbol.

In ranking and numbering arrangement, rank or position of a person from right or left to top or bottom of a row is to determined. Also, rank or position is given and the total number of people are to be calculated. Furthermore, based on the data given, you may also be asked to determine on which floor does the person lives on.

You need to read the statement line by line and thereby apply the cases as explained below. Also, the position of a person can be from any side of the row and rank is also given from the top or bottom of the row.

### Type 1

Total number of people = total number of people before or after the given person in a row + position of that same person from the different side.

Ex: In a row of people, the position of person X from the left-hand side is 23rd and there are 5 people after X in a row. So, how many total people are there in the row?

Here, the total number of people in the row = number of people after X + position of X from the left side.

Thus, total number of person = 23 + 5 = 28

### Type 2

Total number of people = (sum of positions of similar person from both sides i.e. right and left side) – 1

Ex: Ina row of people, the position of X on the left-hand side of the row is 25th while the position of X from the right-hand side of the row is 32nd. How many total numbers of people are there in the row?

Total number of students = (Position of X from light + position of X from left) – 1

= (25 + 32) – 1

= 56

### Type 3

When the position of two people are given from either end and we know the total number of people than two cases are formed when trying to determine the total number of people between these positions.

1. When there is no overlapping, the sum of the positions of the two people from either end < total number of people

2. If there is overlapping, the sum of the positions of the two people from either end > total number of people

So, the number of candidates between two different people = total number of students – the sum of positions of two different people from either end

Ex: There are 52 people in a row. X is at the 13th position from the left side of the row while Y is at 18th position form right side of the row. Find the total number of people between X and Y.

So, sum of positions between X and Y either ends = 13 + 18 = 31 < total number of people

Thus, no. of people between X and Y = total no of candidates – (position of X from a left + position of Y from right)

=> 52 – (13 + 18) = 21

## Number Ranking Reasoning Questions
