This subject book from Springboard Academy is a Mathematics and Reasoning title from the RAS Foundation series, prepared for candidates appearing in the RAS examination conducted by RPSC. Mathematics and reasoning is the one section where accuracy is fully within a candidate's control, and speed comes only from repeated practice on the right question types — so the book pairs short-cut methods with worked examples and practice questions rather than leaving the aspirant with rules alone. It covers the arithmetic and mental ability areas the paper draws on: number system, LCM and HCF, simplification, percentage, ratio and proportion, average, profit and loss, simple and compound interest, time and work, time speed and distance, mensuration, data interpretation, along with reasoning topics — series, coding-decoding, blood relations, direction sense, syllogism, analogy, ranking and arrangement, clock and calendar, puzzles and non-verbal reasoning. The book is aimed at candidates who need to build the section from the basics as well as those revising for speed.
