SSC GD Constable Exam Preparation: Elementary Mathematics

The following pointers have been listed down to help you score above par on the Elementary Mathematics section of the SSC GD Constable 2021 syllabus.

• SSC GD Constable 2021 Syllabus: [Profit & Loss, Percentages, Simple & Compound Interest, Time & Work, Average, Ratio & Proportion, Functions, Linear Equations, Quadratic Equations, Case Study Analysis, Probability, Graphs, Speed & Distance, Number System, Simplification, Time & Work, Partnership, Data Interpretation, Permutation & Combination, etc.]
• Assessing the previous year’s questions papers, the overall difficulty level of the exam was adjudged to be at the easy-moderate level. Further, the elementary mathematics section had a difficulty level of easy, in particular. Out of the 25 questions, try to mark all questions and have an aim of 19-21 questions correct at all costs.
• SI/CI/Profit & Loss is the most important sub-section with 5 questions. After that, Mensuration/Geometry typically carries 2-3 questions and the same goes with Time & Work [3 questions] and Data Interpretation [3 questions]. Algebra, Percentage & Averages, Speed and Distance all generally have a weightage of 2 questions. Rest is miscellaneous. Here is an example from the arithmetic section.

Q. Sugar bag A of 5 kg is mixed with another bag of Sugar B of 4 kg. Sugar A costs 6 per kg and the mixture costs 7 per kg. What is the price of the costlier sugar?

a) 8.04   b) 8.75  c)  8.52   d) 8.25   e) 8.75

Here is an example from the series section.

Q. 23, 25, 29, 37, ?

a) 53   b) 54   c) 55   d) 56   e) 57

•  To get the most out of the above Maths SSC GD Syllabus topic-wise, you must focus on some fundamental portions in the first phase of your SSC GD Constable exam preparation. During this phase, restrict yourself to ratio & proportion, averages, geometry techniques and formulae, simplification, unitary method, divisibility rules, number system and like. In the next phase, you can move on to data interpretation and algebra questions.
• An important trick you can make use of for Data Interpretation questions is to visualise and prepare diagrams or flow charts to highlight the basic information, what you have been asked to find or calculate, logical flow of argument and assess the plausibility of available choices.
• For DI questions, in particular, you will be presented with a bar graph/line chart/pie chart/histogram, etc., a problem statement and choices, for instance, the performance of a company through 3-4 years. Typically, you will be asked to calculate ratios such as profit & loss ratios, profit percentage, loss percentage, etc. Here is an example.

Q. What is the yearly increase in salary through the five years?

a) 5000 b) 4000 c) 6000 d) 7000 e) 8000

Q. What is the average salary earned by Mr Saurav through 2013-2015?

a) 20000 b) 22500 c) 25000 d) 27500 e) 30000
