Anyways, you should not worry because the Civil Service exam – Professional and Sub-professional levels are not difficult like some board exams like CPA and the BAR.

The usual concepts and subjects never change and never update like that of CPA and BAR Exam. Reviewing well will really help you find the best answers. Follow the following tips:

  • Analyze the given question well. Know what is really being asked and don’t go too much or too deep further.
  • Don’t confuse yourself especially when the multiple choices are kinda similar or related to each other. You have to find the ‘best’ option.
  • Apply your chosen answer to the given statement or equation especially in Numerical Reasoning or Math problems. We call it double checking. If it makes sense, then it’s correct.
  • Use elimination method for finding the best answer.
  • Use parallelism and consistency for synonyms and vocabulary.
  • Believe in yourself because you know deep inside you if you can pass the exam or not.

Numerical Reasoning Correct Answers with Solutions and Explanations:

  1. (2) next number in the sequence is 3. Notice that the numbers in the pattern were divided by 3 to get the next number. Therefore, you divide 2187 by 3 you’ll get 729, then the next and so on.
  2. (3) 81 – you can get this by squaring the numbers (1×1=1), (2×2=4), (3×3=9) and so on…
  3. (4) -144 – subtract the 3rd and 1st to get the 2nd number, do the same to the next 3 sets
  4. (1) IR KP – Use the equivalent ascending and descending letters in the alphabet
  5. (2) P15625 – the pattern is the next 2 letters from the alphabet and the number multiplied by 5 to get the next one…
  6. (2) -9 –positive + negative numbers is to subtract them and follow the sign of the bigger number
  7. (3) 124 – positive – negative numbers is to change the sign of the subtrahend and follow the rules in addition
  8. (1) 198 – multiplying numbers with similar signs = positive
  9. (1) -100 – already explained
  10. (1) -80 – dividing numbers with different signs = negative
  11. (4) ¾ + 5/2 + 1/3 – simplify the fractions given and convert the mixed number into improper fraction
  12. (3) LCD is 16 – the denominators are: 8, 4 and 16
  13. (3) GCF is 18 since 36 and 64 are divisible by 18, 9, 6, 3
  14. (3) the answer is 3 because ½ + 2 + ½ = 3
  15. (2) the answer is 6/27 simplified into 2/9
  16. (4) you will get 6 if you cross multiply the fractions
  17. (1) .0075 because ¾ is 75 percent or 75/100
  18. (4) 3.4/100 because percent is n/100
  19. (2) .25 because it is the same as 25/100
  20. (2) 5:4 because is is ½ divided by 2/5
  21. (2) 2,120,000 because 10 to the 6th power is in million
  22. (1) 2,500,000 because it is 25 x 100,000
  23. (3) x = -3 because 5(-3) + 25 = 10
  24. (4) y = 2 because 4 (8) – 2 (2) = 28
  25. (1) x = 9 because 2 (9) + 4(8) = 50
  26. (4) 5 years old – to get it, make a table and derive the equation:

Let x be Sam’s age:

Write the new relationship in an equation using the ages in 5 yrs.


In 5 years, Kit will be three times as old as Cara.

2x + 5 = 3 (x–5 + 5)
2x + 5 = 3x
x = 5

Sam is now 5 years old.

27. (3) 8 years old – again solve it by making a table and derive the equation:

Let x be James’s age now. Add 2 to get the ages in 2 yrs.


Write the new relationship in an equation using the ages in 2 yrs.

In two years, the sum of their ages will be 58.


James is now 8 years old.

29. (2) 360 miles Solution: D= 50 (2) + 4 (65) = 360 miles

30. (1) Original price is P3,062.50

To get it, simply divide P2450 by 80%

    1. It’s an example of question wherein the exact answer is not given among the choices. There are also given items like that from other reviewers. I added that as one of the items given in Math. Like I said, sometimes you only need to find the best and closest answer when the exact answer is not given among the choices.

  28. Hello again! Another way to solve number 2 in numerical reasoning is by adding odd numbers 3,5,7, til 17 to the given sequence of numbers respectively. That is 1 plus 3 = 4; 4 plus 5= 9; 9 plus 7= 16; 16 plus 9= 25; 25 plus 11= 36; 36 plus 13 = 49; 49 plus 15 = 64; and finally 64 plus 17= 81, the answer.

  29. hi! W/ regard to problem solving number 26. The current age of Kit is 10 and Cara is just months old (0 year)? And in 5 years, Cara will turn 5 and Kit is 15 (three times older than Cara in 5 years). Sam is indeed 5 years old now (Kit is twice as old as his friend Sam- 5*2=10). Thank u.

  30. Hi! Please review number 17 in numerical reasoning. I believe 3/4 in decimal form is 0.75, right? So the answer should be number 3 (0.75). Same as 75/100=0.75. Thank u.

    1. Hey you forgot the percent thing 🙂 Yes 3/4 is .75 in decimal form but the question is convert 3/4 % in decimal 🙂 So you have to add 2 zeros, it will make it .0075 as the correct answer 🙂 Tricky I know.

      1. maam paano ako maka avail ng reviewer sa niu?malayo po kasi kami nasa mindanao sa iligan city…so how can avail your reviewer?

      2. Good day Mam,

        I just wanted to ask if still you have a reviewer for this incoming CSE 2015 how can i buy please help me. i need to pass thank you soo much

  31. Hi,
    Would like to correct the #14 question and answer in Numerical Reasoning, it’s not ½ + 2 + ½ = 3.
    See below, the right equation from the practice test.

    14. What is the sum of ½ + 8/4 + 6/12 ? – 1. 15/12

    1. 15/12
    2. 3/12
    3. 3
    4. 3 1/12

    1. 3 is the correct answer because you cannot add directly fractions with different numerators like what you did with your answer 15/12.

      1. ask ko lang poh… s answer key for numerical reasoning… wala pong sagot s number 28?
        Answer ko poh… 1. 91.40… add the score and divide by the total number of exam = 457/5 = 91.40..
        am i right?
        pakipost n lang poh yong answer. thanks.

  32. i need answers for the reading comprehension i hope you can send it now po.
    i just found out your website and i am really amazed with this reviewer.
    thank you!
