SSC CGL 2025 Tier 1 Reasoning PYQ – 15 Sep 2025 Shift 3 (24 Questions with Solutions)

SSC CGL 2025 Tier 1 Reasoning PYQ 15 Sep Shift 3 Question Paper

For SSC CGL aspirants at the previous-year practice stage, this is the General Intelligence and Reasoning section of the Tier 1 paper held on 15 September 2025, Shift 3. It covers analogies, series, coding, ranking and blood relations. Aptitude360 includes a worked solution for every question.

What the 15 Sep 2025 Shift 3 Reasoning section tests

• Word analogy based on the relation between a substance and its use
• Letter-cluster series and number series built on changing differences
• Coding-decoding by letter shifts and letter rearrangement
• Alphabetical ordering and positions of letters in a word
• Row ranking from the left and right ends
• Blood relations, including symbol-coded relations
• Odd one out, address matching and mathematical operator substitution

Key reasoning rules for SSC CGL Tier 1

• Reverse alphabet position: \( 27-p \)
• One person, L-th from left and R-th from right: \( N=L+R-1 \)
• Between two, L-th from left standing left of R-th from right: \( N-(L+R) \)
• Products of consecutive numbers: \( T_{n}=n(n+1) \)
• After operator substitution: \( \times \) and \( \div \) left to right, then \( + \) and \( - \) left to right

How to prepare for SSC CGL reasoning questions

• Write out the differences between terms of a number series before guessing the pattern.
• Draw a family tree with gender symbols for every blood relation question.
• Memorise letter positions from both ends of the alphabet to speed up coding questions.
• In ranking problems, check whether the two positions overlap before subtracting.
