Arrangement problems are an important aspect of the Logical Reasoning curriculum. These are the most prevalent assessments, and they can be found in any entrance exam that includes an aptitude test, such as the CAT. This emphasises the importance of comprehending these types of issues.
There are several types of arrangement issues, including linear, circular, and table or matrix-based complex arrangements.
How to Answer Questions on Matrix Arrangements:
1. Draw a table with the first column devoted to objects or people whose characteristics are stated in the problem.
2. Create a table with the first column devoted to the objects or individuals whose qualities are specified in the challenge. The properties of the object are mentioned in the columns below.
3. Now start reading, putting up the direct information linked with the issue’s object, using ‘+’ to indicate yes and * to indicate no.

One animal of the same species lives in each of the X and Q enclosures. Z and P have the same animal pair. Shalini looks after the following animals:
