The LIC AAO Preliminary Exam 2025 is scheduled to be held on October 3, 2025, and reasoning is one of the most scoring sections. The reasoning, coding-decoding has always held its importance in banking and insurance exams such as LIC AAO, SBI PO, IBPS PO, and Clerk. In the LIC AAO, approximately 4-6 questions are typically asked from this topic. Candidates proficient in coding decoding can score these marks in just a few minutes. Pattern recognition, logical thinking, and quick application are crucial. In this article, we will discuss the most frequently asked coding-decoding questions, step-by-step solution methods, and last-minute preparation tips to help you score full marks in this subject.
What is Coding-Decoding?
Coding-Decoding is a reasoning topic where a word, number, or message is coded in a specific way, and candidates need to decode the logic behind it.
- Coding: Transforming words/letters/numbers into a secret code using a pattern.
- Decoding: Reversing the process to find the original word or applying the same logic to new words.
It tests your analytical skills, logical reasoning, and observation speed.
Types of Coding-Decoding Questions
To score well in RRB PO 2025, you need to be familiar with the major types of coding-decoding. One of the most important and frequently asked is:
Chinese (Sentence) Coding
In this type, complete sentences are coded with random symbols or words. The trick is to compare the sentences and use the common words–common codes principle.
Example:
- “I love coding” → “ka la ma”
- “Coding is fun” → “ma da pa”
Here, the common word is “coding”, and the common code is “ma”.
Therefore, “coding” = “ma”.

Quick Tips to Solve Coding-Decoding Questions in 1 Minute
Identify the Pattern Quickly
The first step is to read the question and observe the examples given carefully. Look for shifts in letters, substitutions, or reversals. If the code is letter-based, check the alphabetical positions (A=1, Z=26). Spotting the logic early will save you precious time.
Use the Alphabet Reference
Memorising the alphabetical order is very helpful. Know both the forward sequence (A=1, B=2, …, Z=26) and the reverse sequence (Z=1, Y=2, …, A=26). This makes it easy to apply shifts without confusion. Quick trick: add for forward shifts and subtract for backward shifts.
Break Down Complex Questions
Some questions may involve more than one step, like shifting letters and then reversing them. In such cases, apply the rules step by step. Writing down the intermediate step on rough paper can help you avoid silly mistakes and improve accuracy.
Practice Common Patterns
Exams like LIC AAO often use similar patterns repeatedly. These include forward/backward shifts like +2 or -3, vowel–consonant rules, or number-to-letter mapping (A=1, B=2). Practising at least 20–30 questions daily will make you familiar with these styles so you can solve them instantly.
Use Elimination for Tricky Questions
When you find a tough question, don’t waste time solving it fully. Instead, check the options. Eliminate the ones that don’t match the pattern. Often, testing one or two choices is enough to arrive at the correct answer faster.
Time Management
Speed is as important as accuracy. While practicing, set a timer and try to solve each question in 30–45 seconds. In the exam, don’t get stuck on a difficult one. Skip it and come back later if time allows. This ensures you don’t miss out on easy marks.
