Input-Output Reasoning Questions For Bank Exams

Input-output reasoning questions are an important component of the reasoning section in bank exams. These questions assess a candidate’s ability to analyze and transform sequences based on specific rules or patterns. Mastery of Input-Output questions is crucial for scoring well, as they require both logical thinking and speed. By understanding the underlying principles and practising various types of Input-Output scenarios, candidates can enhance their problem-solving skills and increase their overall exam performance.

Input-output is a type of logical reasoning question where you are given a set of specific words in a particular sequence. The sequence of these words keeps changing with each step. The last or final sequence of words needs to be identified based on the underlying logic of the initial sequence of words and the way the sequence changes with each step. In this article, we are going to discuss the Input-Output reasoning questions for bank exams.

Solutions (1-5): Decoding the logic:
The logic followed here is: In first step the highest number is arranged from the left side after subtracting 2 with it. And in the second step the word is arranged in the reverse alphabetical order after the number arranged in the first step. This process is repeated till the last step.

Solutions (06-10): In this input-output question two numbers are arranged in each step following a certain pattern. Let us understand the logic behind it-

* Even numbers are arranged at the right end, from left to right in ascending order after adding one to each number (Numbers are picked from lowest to highest).

* Odd numbers are arranged at the left end, from right to left in ascending order after the digits are interchanged within the number (Numbers are picked from lowest to highest).
