Where to Find and Use Arun Sharma's Quantitative Aptitude 10th Edition
I have been working with competitive exam preparation materials for over eight years, mostly across Indian banking, CAT, and government recruitment pipelines. The book everyone asks about is Arun Sharma's Quantitative Aptitude, and the 10th edition is still the most commonly referenced version. I am going to explain how to get it, what is actually useful inside it, and where people typically waste time. The book covers percentages, profit and loss, time and work, time and distance, number systems, algebra, geometry, mensuration, and modern math topics like permutations, combinations, and probability. It is not a textbook in the academic sense. It is built around question banks segmented by difficulty level, with shortcuts that work for timed exams but sometimes skip over the underlying logic. That is intentional. The book is designed for test-taking efficiency, not conceptual purity.
Arun Sharma Quantitative Aptitude 10th Edition Pdf Google Drive
You will find multiple uploads of this book on Google Drive links shared across Telegram channels, Reddit threads, and coaching affiliate sites. Most of the links are mirrors or re-uploads from the original leak years ago. The file is typically between 40 to 60 MB depending on whether it includes the answer key appendix or extra practice sheets. A few versions are corrupted in the later chapters, especially the set theory and probability sections, because they were scanned from different source copies and stitched together poorly. My workaround for the corrupted files was straightforward. I downloaded three different Drive links, opened each PDF, and compared page 312 through 340 across all three versions. Two of them had clean scans in that range, and I merged the good pages using a free tool like PDF24 or SmallPDF to patch the broken chapter. It takes about twelve minutes and saves you from buying the physical copy just to fill gaps. I also keep a screenshot backup of each patched page in a folder labeled clearly, so if the merge tool distorts any text during reconstruction, I can swap it back manually. Here is something most people miss about this book. The shortcut methods in the early chapters, like the percentage change tricks and the ratio-based time-work shortcuts, are genuinely fast once you internalize them. But the algebra section shortcuts for solving quadratic equations or the approximation tricks for DI sets often break under edge-case numbers. I learned this during a mock test when a shortcut for finding the LCM of two expressions gave me a wrong answer because the factors involved a prime greater than 13, which the shortcut silently skips over. The conventional method always works. The shortcut is a speed hack, not a replacement for fundamentals. Use it only after you can solve the problem the long way without looking at the solution.
Another thing nobody warns you about. The 10th edition revised some of the question patterns from the 9th edition. If you are using an older edition that someone re-uploaded, do not assume the questions are identical. The numbering is mostly the same, but approximately 8 to 12 percent of the questions were rewritten or renumbered to reflect changes in exam patterns. Cross-check the edition year on the copyright page before relying on a particular question for practice. Downloading the PDF is simple enough. You search for the exact title, sort results by relevance, and click a Drive link. If the Drive requires permission, look for a "Request access" button and wait. Some files are public. Some are restricted to "Anyone with the link." If a link fails after three attempts, move on. Most of these files rotate or get taken down. Telegram channels are usually faster for updates because they re-host the file within hours of a takedown. I would be dishonest if I did not mention the limitations. The book has a bias toward certain exam types. The CAT-level questions are solid, but the banking PO-level DI sets feel slightly underrepresented compared to what actually appears in IBPS or SBI exams. The modern math section is thorough on paper but thin on the application-based word problems that recent exams have started favoring. Also, the answer explanations in the back are sometimes abbreviated to the point where you cannot follow the step between two lines. This is especially true for the geometry proofs. You will spend more time reverse-engineering the solution than learning from it.

If you find those gaps frustrating, supplement with RS Aggarwal's Quantitative Aptitude for the explanatory depth, or use test series platforms like Oliveboard or Testbook for the DI sets that mirror current exam patterns. Arun Sharma is best used as a question drill manual rather than a standalone learning resource. Read the concept summary at the start of each chapter, then immediately move to the practice questions. Skip the theoretical derivations. They are useful for academics, not for a 2-hour exam where you need to recognize the pattern and execute the method in under 90 seconds per question. The file itself is legal if obtained from an authorized source, though most Drive links circulate through unauthorized channels. If you can afford the physical copy, buy it. The print quality is better, the pages do not shift during scanning, and the answer key is easier to reference while practicing. If cost or location makes that impossible, the PDF route works fine provided you verify the edition and patch any corrupted pages before relying on them for timed practice sessions.
