Exam Q 142024Previous Year Pattern
In a certain code language, the positions of letters in the English alphabet are used to form a pattern. If we reverse the alphabet (Z=1, Y=2, X=3, ... A=26) and then apply the following rule: 'For every consonant, add 3 to its reversed position value; for every vowel, subtract 2 from its reversed position value', what will be the code value for the word 'BRIGHT'?
Exam Q 152024Previous Year Pattern
In a modified alphabet where every consonant is replaced by the letter that comes 3 positions after it, and every vowel is replaced by the letter that comes 2 positions before it, what is the 4th letter of the modified word for 'STRENGTH'?
Exam Q 162024Previous Year Pattern
In a certain code, the positions of letters in the English alphabet are reversed (A=26, B=25, C=24, ... Z=1). If the word 'REASONING' is coded using this system, what is the sum of the coded values of the 2nd, 5th, and 8th letters of the coded word?
Concept Notes
Alphabet Test— Rules & Concept
Core ConceptRead this first — the foundation of the topic
Each letter has a fixed position
A=1, B=2, C=3... Questions can ask about positions from left (A=1) or right (Z=1, Y=2, X=3). Most SSC questions use left-side positioning
Key Rules
First, memorize that A=1 and Z=26 from the left. From the right, A=26 and Z=1. The formula for right position is: Right Position = 27 - Left Position. For example, M is 13th from left, so from right it's 27-13=14th position
Common question types include
finding positions of letters, arranging letters in alphabetical order, identifying middle letters in sequences, finding letters at specific positions after rearrangement, and determining which letter comes before or after a given letter.
ShortcutsUse these to save 30–60 seconds per question
Worked ExampleSolve this step-by-step before moving on
1
Step 1
Write down the letters in PLANET: P, L, A, N, E, T
2
Step 2
Arrange these letters alphabetically by comparing their positions in the alphabet:
A=1, E=5, L=12, N=14, P=16, T=20
3
Step 3
Alphabetical order becomes: A, E, L, N, P, T
4
Step 4
Count positions: 1st=A, 2nd=E, 3rd=L
5
Step 5
Answer is L
Another Shortcut: For finding positions quickly, remember these landmark letters: E=5, J=10, O=15, T=20, Y=25. These help you estimate nearby letter positions without counting from A.
Exam PatternsWhat examiners ask — read before attempting PYQs
SSC typically asks 1-2 alphabet test questions. Common formats include word arrangement, finding missing letters in sequences, and position-based problems. Questions often combine alphabet knowledge with logical sequences.
Exam TrapsCommon mistakes students make — avoid these
Students often confuse left and right positions. Always clarify whether the question asks for position from left (standard) or right. Another mistake is miscounting when arranging letters - always double-check your alphabetical order.
Practice writing the alphabet backward to strengthen right-position calculations.
Key Points to Remember
English alphabet has 26 letters with A=1, B=2... Z=26 from left side
Right position formula: 27 - Left position (A=26, Z=1 from right)
