A Matrix is a grid-like structure made of rows and columns. In the context of reasoning, it is a table used to represent data or patterns. Rows are the horizontal lines that run from left to right. Columns are the vertical lines that run from top to bottom. Each box in the grid is called a cell. These cells contain numbers, letters, symbols, or shapes. In competitive exams like UPSC, the Matrix topic usually appears in two ways. The first type is 'Coding-Decoding' using two tables.

This concept requires identifying a visual rule. Shapes in a row might change according to a pattern. For instance, in the first row, a circle has one line. In the second row, it has two lines. In the third row, it should have three lines.
This concept requires identifying a visual rule. Shapes in a row might change according to a pattern. For instance, in the first row, a circle has one line. In the second row, it has two lines. In the third row, it should have three lines. Common rules include rotating the shape, changing its size, or moving an arrow. Example: An arrow pointing Up, then Right, then Down shows a 90-degree clockwise rotation.
This involves finding codes for words using two provided grids. Each letter has a unique coordinate. For example, if Matrix 1 shows 'B' at row 1, column 2, the code for B is 12.
This involves finding codes for words using two provided grids. Each letter has a unique coordinate. For example, if Matrix 1 shows 'B' at row 1, column 2, the code for B is 12. To solve faster, check the options from the last letter of the word to the first. This often helps eliminate three wrong choices instantly. Example: If the word is 'TIN', look for the code of 'N' in the options first.
This is used for 'who-lives-where' style puzzles. You create a table with names as rows and attributes (like cities) as columns. If a person A does not live in city B, put an 'X' in that cell. If they do, put a 'Tick'.
This is used for 'who-lives-where' style puzzles. You create a table with names as rows and attributes (like cities) as columns. If a person A does not live in city B, put an 'X' in that cell. If they do, put a 'Tick'. Once a 'Tick' is placed, all other cells in that row and column become 'X'. Example: If A is in Gujarat, then B, C, and D cannot be in Gujarat.
