Numerical Reasoning Practice Test – Civil Service Exam

We are sharing here the best Numerical Reasoning practice test for the Civil Service exam. This page includes the most common questions for this part of the CSE. Just like our other posts, we also include effective tips and techniques to get the best and correct answer to every question.

Eventually, the PDF version of this whole online reviewer will be done and the release will be announced in this site. Meanwhile, you can just use this free online reviewer because it contains the complete scope of the Civil Service exam anyway.

Even though there is no calculator allowed, Quantitative Numerical Reasoning is not so difficult in the Civil Service exam especially if the examinee is very good in Math and logic.

It involves mainly with the basic Mathematical processes – addition, subtraction, multiplication and division for fractions, ratios, equations, and some problem solving or word problems. There are many series and sequence-questions as well.

Tips to Pass the Numerical Reasoning Test in the Civil Service Exam

  • Relax and just enjoy answering your Math quizzes. If you’re relaxed, you’ll never lose focus and that is so important.
  • Know the basics of Math like adding, subtracting, multiplying and dividing fractions, ratios, decimals, and equations. If you know these concepts, you’ll surely get everything. Otherwise, you won’t know what to do. (see our techniques below)
  • You can use scratch paper for your computations and solutions. Note that you will also have to pass your scratch papers.
  • Love Math because it is easy for someone who loves Math.
  • Focus in solving problems. Think, analyze, and solve.
  • Pray before the exam. It always helps.

Numerical Reasoning Test Techniques

For the purpose of reviewing better, I’m going to share here some concepts of Math because like I said, you have to know the basics before you solve everything. I know I have to share these because this is an online reviewer in the first place. Reviewing is practice.

Decimals:

For Addition and Subtraction, it is very simple and easy. Just line up the given numbers though their decimal point. If it has no decimal point, put one or convert one. Put zeros to complement the numbers if needed.

I remember there are many questions about decimals when I took the exam. Lots involve with multiplication and division. Same with fractions, I think I enjoyed that part so much because fractions are my thing.

  • Examples: 

5.98 + 6 + ¾ = ______

1.25 + 1.5 + 7.875 ______

25 – 8.35 – 1.3 + _______

addition subtraction decimals

For Multiplication, don’t take it too hard because it is very simply too. Just multiply the numbers and count the decimal places to the right of the given numbers then move in that decimal (count) from the right answer to the left.

  • Example: 3.05 x 1.4 =?
multiplication decimals

For Division, you have to divide the classic way by making the divisor a whole number. You need to move the decimal place to the right to make it a whole number then do the same way with the dividend. Add zeros to the dividend if necessary. See example below.

  • Example:  0.35 ÷ 1.4 (0.35 is the dividend and 1.4 is the divisor here)
division decimals

Fractions:

Some of the questions in Math and Quantitative Numerical Reasoning tests involve with fractions because they are also related to decimals, percent, mixed numbers and algebraic expressions. Again, if you master solving fractions, it will be a great edge for you.

Addition and Subtraction of Fractions

In this process, the easiest way is to always simplify the fractions by finding the LCD aka least common denominator, then apply the operation. If the result is improper fraction (numerator is bigger than denominator), simplify it too by giving the mixed number. Watch this helpful video.

How to Multiply and Divide Fractions?

To multiply fractions is easier. Just multiply both the numerator then multiply both the denominator. Simplify the product is you must.

  • Example: ½ x ¾ = 3/8

To divide fractions, inverse the second fraction then we follow the rules in multiplication. You can also cross-multiply the given fractions.

  • Example: How many 1/3’s are there in ½?
division fractions

Converting Fractions to Decimals and vice versa:

In converting fractions to decimals, just divide the numbers and round them off.

  • Examples:

1/3 = .333
5/8 = .625
7/8 = .875

Another way is to find a number to multiply by the denominator to make it 10, 100 or 1000…

  • Example:

Positive and Negative Numbers:

Addition and Subtraction

  • Positive + Positive = Positive
  • Negative + Negative = Negative
  • Positive + Negative = Subtract the two and use the sign of the bigger number
  • Positive – Negative = Change the sign of the Subtrahend and follow the rules of Addition
  • Negative – Negative = Change the sign of the Subtrahend and follow the rules of Addition

Multiplication and Division:

  • Multiplying and dividing numbers with similar sign equals Positive ( + x + = +) and (– x – = + )
  • Multiplying and dividing numbers with different signs equals Negative ( + x – = – ) and ( – x + = – )

Number Series and Sequence:

There are also logical sequence and number series in this Math exam. Of course you have to find the next number from the pattern. You will know the right answers by applying the same method you used in a sequence to get the next number or the next.

Examples:

3, 5, 7, 9, 11, 13
2, 4, 8, 16, 32, 64, 128

Problem Solving:

We cannot miss to include this scope here because every Math exam has problem solving. The key to find the correct answers is to analyse the given case well and understand what is being asked. Apply your magical Math logic.

    good bless

  3. Mam Good morning! Mam gusto ko po sana mag avail ng civil service reviewer kaya la ng po wala po kasi akong credit card, ano po ang aking gagawin ?

  4. Another concern lang po, number 17. Sa answer key po, 0.0075. Pero di po magcoincide sa explaination. if 3/4% is = to 75% or 75/100 then it should be 0.75? Tama po ba?

    1. 0.0075 is the correct answer because, 3/4 = 0.75 . then, to get the percentage, divide it by 100 . so, 0.75/100 = 0.0075 .

  5. Nalilito lang po ako. Number 13 sa Numerical Reasoning. Sa Sample Test 36 and 54, sa answer key 36 and 64. Pakilinaw po Please.

  6. I am very thankful sa 1taker.com because i already passed the CSE last april 2014 and now i am planning to take the professinal exam this coming april 2015, still hoping and believing that i can make it with 1taker help and support. 😀

      1. 3/4% is equal to 0,75% beacause 3/4 is equivalent 75/100 or 0.75 , thats why when you transpose3/4% to decimal form you can get o.oo75..

        just like for example:
        3 and 3/4% is equivalent to 3.75% so when you transpose it to decimal form, you can get 0.0375…

        thats what i understand in number 17 🙂

  12. di ba ganito gagawin sa number 18?

    Example: Express 62.5% as a fraction

    Step 1: Write down:
    62.5/100

    Step 2: Multiply both top and bottom by 10 (because there is 1 digit after the decimal place)

    62.5/100 = 625 /1,000

    (See how this neatly makes the top a whole number?)

    Step 3: Simplify the fraction (this took me two steps, you may be able to do it one!) :

    625 /1,000 = 25/40 = 5/8

    Answer = 5/8

    paano po ba?

      1. Hi, just a clarification,

        RE: 17. What is the decimal form of ¾ %?
        Answer: .0075 because ¾ is 75 percent or 75/100.

        Manually, I got 3.) .75.
        To check using calculator and excell conversion, I was correct.
        75 divided by 100 is also .75.

        Why is your answer .0075? Have you divided it again over 100?

        Thank you!

        1. 3/4 is equal to 0.75
          thus, 3/4% is 0.75%
          converting fraction by moving decimal point to the left 2 times..
          you will get 0.0075.

          tingin ko po, ganun un.. 🙂

        2. 3/4 percent is different from 3/4 as fraction.
          3/4=75 percent
          while 3/4 percent = .75 percent
          kindly check again.
          thanks and hope mas clear..

    1. Tama po ang approach niyo pero express as fraction ang tanong..although yung example niyo na 62.5 percent to fraction. Ang approach ko jan since na 62.5 percent is equal to .625 as decimal pwede po na 62.5/100 same as .625

      #18 same po..

      3.4percent =.o34
      So pwede na 3.4/100 same as .034

      Thanks

  13. Cathy scored 85, 87, 90, 95, and 100 in her Math exams. What will be her average grade in Math from this period?
