Arithmetic Questions and Short Tricks for ADRE, APSC and Assam Police

Arithmetic is the backbone of the quantitative aptitude section in almost every Assam government recruitment examination. ADRE Grade 3 and Grade 4, Assam Police Constable and Sub-Inspector, APSC CCE, DHS, DME, Gauhati High Court, SSC and Railway papers all test the same core arithmetic chapters, and these questions often decide whether a candidate clears the cut-off.

On axomexam the subject is organised chapter by chapter so that you can build speed and accuracy step by step. Every topic links to a practice set with worked solutions in English and Assamese, so you learn the exact method the examiner expects instead of memorising individual answers.

Why arithmetic decides your mathematics score

Numerical ability usually carries 15 to 25 questions in Assam recruitment papers and arithmetic forms the largest share of that block. The questions are formula-based and repetitive, which means a well-practised candidate can solve them quickly and score reliably. Because the same chapters repeat across state and central exams, one solid round of arithmetic preparation pays off in several tests at the same time.

Arithmetic chapters covered on axomexam

• Number System and Simplification — divisibility rules, HCF, LCM, remainders, surds and fast calculation.
• Percentage — increase and decrease, successive change and percentage-based word problems.
• Ratio and Proportion — direct and inverse proportion and division of quantities.
• Profit, Loss and Discount — cost price, selling price, marked price, successive discounts and dishonest-dealer problems.
• Average — simple average, weighted average and average age and speed problems.
• Time and Work — efficiency, work and wages and pipes and cisterns.
• Time, Speed and Distance — relative speed, problems on trains, boats and streams.
• Simple and Compound Interest — instalments, growth and depreciation.
• Mensuration — area, perimeter, volume and surface area of standard shapes.
• Problems on Ages, Partnership and Mixture and Alligation.

Most repeated arithmetic chapters in ADRE and Assam Police

Based on past papers, the following chapters appear again and again and deserve extra revision: percentage, profit and loss, ratio and proportion, average, time and work, time–speed–distance, simple and compound interest, and mensuration. If you are short on time, master these eight first.

How to prepare arithmetic for Assam exams

• Learn the formula or short method for a chapter before attempting its questions.
• Solve 15 to 20 questions per topic every day and time yourself with a stopwatch.
• Keep a formula notebook and revise it for five minutes before each practice session.
• Read the explanation for every wrong answer and note the exact reason for the mistake.
• Re-attempt the same set after three days and check whether your accuracy has improved.
• Take a full timed mock test every week to get used to exam-day pressure.

Common mistakes to avoid

• Rushing through reading and misreading values such as 'less than' and 'more than'.
• Skipping the units and mixing percentages with absolute numbers.
• Solving every question the long way instead of using short tricks.
• Ignoring mensuration because it looks difficult — it is one of the most predictable chapters.
