SSC CGL 2025 Tier 1 Reasoning PYQ: 23 Sep 2025 Shift 2 Paper Practice

This set builds core reasoning skills in coding, series, analogies and syllogisms through the General Intelligence and Reasoning section of SSC CGL 2025 Tier 1, held on 23 September 2025, Shift 2. The questions come from the actual paper and also include short arithmetic puzzles. Aptitude360 presents it as a sectional set so you can practise this shift's reasoning on its own.

Question types in the 23 Sep Shift 2 Reasoning section

• Matching an identical postal address and arranging seminar cities by date
• Symbol-operation puzzles where a hidden rule links pairs of numbers
• Number analogies, odd one out and number series built on doubling patterns
• Letter series and coding-decoding by shifting each letter forward
• Syllogism with a single statement chain and word formation from a given word
• Roll-number questions on digital root and matching centre codes
• Short arithmetic: HCF and LCM, speed of a train, profit on cost price, equal sharing of a fixed total

Key formulas and rules for SSC CGL Reasoning arithmetic

• HCF and LCM of two numbers: \( \text{HCF}\times\text{LCM}=a\times b \)
• Speed: \( \text{Speed}=\dfrac{\text{Distance}}{\text{Time}} \)
• Selling price at profit P%: \( SP=CP\times\dfrac{100+P}{100} \)
• Triangular numbers: \( T_{n}=\dfrac{n(n+1)}{2} \)
• Digital root of a positive integer: \( dr(n)=1+\left((n-1)\bmod 9\right) \)

Reasoning concepts worth revising for this shift

• Alphabet positions for quick letter shifting in coding questions
• Venn diagram method for checking whether a conclusion definitely follows
• Common series patterns: doubling plus a constant, squares, cubes and running sums
• Word-to-code mapping by finding words that repeat across coded sentences

Revision tips for SSC CGL Tier 1 Reasoning

• Memorise letter positions so coding and letter-series questions take seconds
• For symbol puzzles, test each candidate rule on every given pair before choosing
• In address matching, compare the PIN code and flat number first to eliminate options
