Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 15-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

About this test

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

Applying a given rule quickly, whether it is a letter code, a swapped operator or a syllogism statement, is what this set trains. It reproduces the General Intelligence and Reasoning section of the SSC CGL 2025 Tier 1 exam from 15 September 2025, Shift 1. On Aptitude360, every question comes with step-by-step working.

Question types in the 15 Sep Shift 1 Reasoning section

  • Coding-decoding with letter shifts, applied to fruit names and other common words
  • Letter-cluster series and number series with growing multiplicative steps, plus a wrong-term question
  • Symbol and operator substitution followed by arithmetic evaluation
  • Blood relations, including a relative described through the mother's side
  • Syllogisms that combine 'No' and 'Some' statements, assumptions and statement-conclusion items
  • Address matching, word formation, letter selection from a sentence and alphabet position products
  • Geometric progression terms, odd one out and simple cost calculations

Concepts worth revising from this paper

  • BODMAS order after operators have been interchanged
  • Using the alphabet position values of A to Z to form sums and products
  • The difference between an assumption, which must already hold, and a conclusion, which must follow
  • Pairing a 'No' statement with a 'Some' statement, as in 'Some squares are triangles', to reach a valid 'some are not' conclusion

How to prepare these SSC CGL Reasoning topics

  • Rewrite the expression with the real operators before calculating in substitution questions
  • Check a coding pattern on two or three letters, in both directions, before applying it to the full word
  • Use Venn diagrams for every syllogism, especially when a statement starts with No
