In the subsequent sections you will get a detailed study plan for SSC CPO Quantitative Aptitude which covers below topics:


SSC CPO Exam pattern and Expected Cut off:

Note that there will be just 1 exam, which will be common for recruitment to all the posts mentioned above. Let us now take a look at the exam pattern.

S.No. Subject / Section No. of Questions Max. Marks Test Duration
1 General Intelligence and Reasoning 50 50 2 hours
2 General Knowledge and General Awareness 50 50
3 Quantitative Aptitude 50 50
4 English Comprehension 50 50
Total 200 200

There is penalty of 0.25 marks for each incorrect answer. Expected Category-wise overall cut off for SSC CPO SI Male and Female candidates are as follows:

Category Cut Off 2016 Expected Cut Off

Due to Consolidate timing and no sectional cut off it is must for candidates to prepare a well planned exam strategy which will guide you throughout your journey for paper I of SSC SI CPO 2017. In subsequent sections you will get trend analysis and more.

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.

Based on the trends and cut off marks, an exam strategy and detailed study plan to cover important topics under SSC CPO Quantitative Aptitude section for Paper I 2017 is discussed below. 


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. 


Study plan and Important Topics for SSC CPO Quantitative Aptitude

To complete the syllabus, follow the given detailed study plan which gives you an idea about types of questions asked from various topics from Quantitative Aptitude syllabus of SSC CPO Paper I. Chapters in the below study plan are ordered on the basis of increasing complexity. If you study Chapters numbered 1 to 3, you will be able to solve 24 questions which completes your first target.

S. No Chapter Topics Remarks
1 Numerical Aptitude(Expected Questions: 5) Operations on Integers, Decimals and Fractions 1. Required in almost all Arithmetic problems so master your calculations first.2. Also learn squares and cubes of first 20 natural numbers to speed-up the calculations.
