Railway Ganit (रेलवे गणित), by Aditya Ranjan Sir and published by Aditya Ranjan Publications, is a Hindi-medium mathematics question book for Railway Recruitment Board examinations. The complete book is written in Hindi (Devanagari script), so aspirants preparing in the Hindi medium can practise maths in their own language. This is the 3rd Edition. The book compiles all the questions asked by RRB so far (RRB द्वारा अब तक पूछे गए सभी प्रश्न) — more than 3500 MCQs — arranged chapter wise, type wise and level wise. That three-way arrangement is what makes a question collection usable: an aspirant can drill a single chapter, focus on one question type, or work up through difficulty levels, rather than meeting questions in the order the papers happened to set them. Smart approach and short tricks are given alongside, which matter in railway papers where the maths is rarely hard but the time is short. It is useful for NTPC, RPF SI, RPF Constable, ALP, Technician, Group-D, RRB JE and other railway examinations.
