Ranking and Order
Ranking and Order is a core topic in logical reasoning. It involves arranging people or objects based on specific qualities. These qualities can be height, weight, marks, or their position in a line. The main goal is to find the exact position of a person or the total number of people in a group. This topic tests your ability to process multiple pieces of information at once. You must link different clues to build a complete picture.

This concept helps find the total number of people in a row when one person's rank is known from both ends. You add the rank from the left and the rank from the right, then subtract 1.
This concept helps find the total number of people in a row when one person's rank is known from both ends. You add the rank from the left and the rank from the right, then subtract 1. Example: If Ravi is 10th from the left and 15th from the right, the total is (10 + 15) - 1 = 24.
When the total number of people and a person's rank from one side are known, you can find their rank from the opposite side. Subtract the known rank from the total and add 1.
When the total number of people and a person's rank from one side are known, you can find their rank from the opposite side. Subtract the known rank from the total and add 1. Example: In a row of 40 students, if Sita is 12th from the top, her rank from the bottom is (40 - 12) + 1 = 29.
This involves comparing traits like height, age, or marks among different people. It is best solved by creating a sequence. Example: If A is taller than B and C is taller than A, the order is C > A > B.
