Introduction of Inequality

In such types of questions of Inequality, a group of elements is given with a certain coded relationship denoted by <, >, =, ≤, ≥ and ≠.

To understand the symbols, let us discuss the meaning of the given symbols:

• ‘X > Y’; Here, the symbol ‘>‘ means ‘greater than’, hence the relation shows that X is greater than Z.
• ‘X < Y’; Here, the symbol ‘<‘ means ‘smaller than’, hence the relation shows that X is smaller than Z;
• ‘X = Y’; Here, the symbol ‘=’ means ‘equal to’, hence the relation shows that X is equal to Z;
• ‘X ≤ Y’; Here, the symbol ‘≤’ means ‘either smaller than or equal’, hence the relation shows that X is smaller than or equal to Z;
• ‘X ≥ Y’; Here, the symbol ‘≥’ means ‘either greater than or equal’, hence the relation shows that X is greater than or equal to Z;
• ‘X ≠ Y’; Here, the symbol ‘≠’ means ‘not equal’, hence the relation shows that X is not equal to Y.
