Trend Analysis for SSC CPO Quantitative Aptitude
First step for preparation is to find out the expected number of qu
estions from different topics of SSC CPO Quantitative Aptitude test based on the previous year papers. We have prepared a trend analysis chart based on analysis of last year papers of SSC CPO Paper I, 2016.
Unit Topic 2016 Expected Data Interpretation Bar Graph/ Pie Graph 10 10 Ratios & Percentage Simple and Compound Interest 2 9 Discounts, Profit & Loss 4 Mixtures and Partnership 3 Algebra Formulas from algebra 3 7 Formulating and Solving Linear and Quadratic Equations 4 Numerical Aptitude Averages, Factors & Multiples 3 5 VBODMAS, Round off and approximations, Laws of exponents 3 Geometry Circles, Triangles and Rectangles 3 5 Lines, Angles and Polygons 2 Trigonometry Height & Distance 2 5 Solving Equations 2 Measurement & Rates Pipes & Cisterns 3 5 Problems on Time, Distance & Speed and Trains Work and Ages 2 Mensuration Problems based on 2D and 3D mensuration 4 4 Total 50 50
This table gives an idea of different topics asked from various units in SSC CPO Paper I Quantitative Aptitude section, based on the SSC CPO Quantitative Aptitude syllabus. We expect the same trend will hold for SSC CPO 2017 Paper I.
Exam Strategy for SSC CPO Quantitative Aptitude
Solving quantitative aptitude problems takes a little more time than questions from other 3 sections and if you are able to get accurate results then it can be your scoring subject.
- Time limits: You are given total 120 minutes to solve complete test consisting of 200 questions which gives you 36 seconds per question. However, you should aim for a total of 40 minutes to spend on this SSC CPO Quantitative Aptitude section.
- First Target: Assign 40 minutes for Quantitative aptitude section and set your first target to solve 24 questions with 100% accuracy. Then you will be able get about 24 marks from this section.
- Second Target: Once you are able to achieve the above, you should start focussing on studying other chapters and also on increasing your speed. Ideally, you should be able to attempt about 30 – 32 questions with 90% accuracy in 25 minutes. This will give you a good score of about 27 marks. Once you have achieved this too, then go for more and try to attempt 35 questions in 35 minutes with 90% accuracy. However, you will need to decide if you wish to continue spending time on this section, or some other.
- It is suggested before you start, you should take mock papers of SSC CPO Quantitative Aptitude section for I so that you can easily point out the topics in which you need to work harder.
