RAS question
In a certain code, TIGER is written as REGIT. How will HORSE be written in the same code?
Correct answer: (C) ESROH.
In this coding pattern, HORSE is written as ESROH because the word is reversed letter by letter.
Explanation
The coding pattern changes TIGER into REGIT through a complete reversal of letter order, not through letter substitution: T-I-G-E-R becomes R-E-G-I-T. Applying that rule to HORSE gives the right-to-left sequence E-S-R-O-H. Therefore, HORSE becomes ESROH. Coding-decoding in reasoning checks whether a candidate can identify the actual operation used in a pattern instead of guessing from surface similarity. NCERT's Learning Outcomes document frames assessment around competencies such as applying knowledge, problem solving and critical thinking, and coding-decoding uses that small but important skill: spotting and applying a rule consistently.
Why the other options are wrong
- (A) HORCE keeps most of the original order and only changes the final letter, so it does not follow the full reversal seen in TIGER to REGIT.
- (B) ERSHO begins with the right first two letters after reversal, but the remaining letters are in the wrong order; the full reverse of HORSE is ESROH.
- (D) SEROH places S before E, while a right-to-left reading of HORSE must start with E and continue as ESROH.
Concept
Coding-decoding under Reasoning and Mental Ability involves recognition of simple positional patterns. It recurs in RAS because such questions quickly measure rule detection and consistent application under time pressure.
