RRB NTPC 2026 Reasoning Booster: Puzzles, Seating & Coding-Decoding — 500 MCQs

500 reasoning questions for the RRB NTPC computer-based tests, on the types that cost the most time — puzzles, seating arrangements, coding-decoding and statement-conclusion — each with the method first and a worked answer after.

General Intelligence and Reasoning carries 30 questions in CBT-1 and 35 in CBT-2. This booster covers its puzzle-and-logic half; each chapter opens with how to read the clues, what to draw and the usual traps, then gives a worked example and practice questions, many in sets of five on one set of directions, as the tests present them.

Ten chapters: seating arrangement in a row; around a table; floor and scheduling puzzles; comparison, order and ranking; coding-decoding with letters and numbers; sentence codes and mathematical operations; syllogism; statement and conclusion with inequalities; blood relations; and direction sense. A mixed test of 30 questions ends the book. 82 pages.

Every question was written for this book; no question from any examination paper is printed here. Each puzzle was checked by computer to have exactly one solution, and 490 of the 500 answers were solved a second time by an independent program; the other ten were checked by hand. This book is independent and is not published, approved or endorsed by the Railway Recruitment Boards or the Ministry of Railways.
