RAS question
If CERTAIN is coded as 3-5-18-20-1-9-14, how is RELATED coded?
Correct answer: (D) 18-5-12-1-20-5-4.
In the A1Z26 alphabet-position code, RELATED is coded as 18-5-12-1-20-5-4.
Explanation
The code used for CERTAIN is the direct alphabet-position pattern: each letter is replaced by its place in the English alphabet. Boxentriq describes the standard A1Z26 convention as converting each letter to its numeric equivalent in alphabetical order, with A=1, B=2, C=3, and so on. Applying the same rule to RELATED gives R=18, E=5, L=12, A=1, T=20, E=5 and D=4. Therefore the complete code is 18-5-12-1-20-5-4. Nothing is reversed, shifted or paired; the question only tests whether the pattern from CERTAIN is carried forward consistently to the new word.
Why the other options are wrong
- (A) This option uses 19 for the fifth letter, but the fifth letter of RELATED is T, whose alphabet position is 20, not 19.
- (B) This option assigns 2 to A in the fourth position, although A must be coded as 1 under the given alphabet-position rule.
- (C) This option begins with 17, which would match Q, while RELATED begins with R and R is 18.
Concept
This tests letter-to-number coding under the standard alphabet-position pattern. Such questions recur in RAS reasoning because they check quick pattern recognition and careful positional mapping without requiring any external knowledge.
