Logical Reasoning Solved Examples 

Now that we are familiar with the types of questions we may come across under this category, let us also go through some important solved examples based on logical reasoning-

Q. DNN, FPP, HRR, _____, LVV

  1. GRR
  2. GSS
  3. JTT
  4. ITT

Explanation: The 1st letters are in alphabetical order, with a letter skipped in between each segment: D, F, H, J, L. The 2nd & 3rd letters are repeated; these letters are also in order with a skipped letter as was in the previous case: N, P, R, T, V.

Thus, the answer is C. 

Q. Find the next number in the sequence: 16, 30, 54, 88, 132…

  1. 186
  2. 188
  3. 190
  4. 206

Explanation: Logic is: difference is 14, 24, 34, 44, 54….

Next term should be 132 + 54 = 186

Thus, the answer is A.

Q. Statement 1: Pens cost more than pencils.
Statement 2: Pens cost less than erasers.
Statement 3: Erasers cost more than pencils and pens.
If the first two statements are true, the third statement is

  1. True
  2. False
  3. Uncertain
  4. Cannot be determined 

Explanation: If the first two statements are true, then Erasers are the most expensive of the three stationery items.

Thus, the Answer is A.

Q.Dan is Joshua’s son and Guy’s brother. Margaret is Guy’s mother and Judy’s daughter. Which of the statements below is definitely true?

  1. Judy is Dan’s mother-in-law
  2. Margaret is Dan’s mother
  3. Judy is Joshua’s grandmother
  4. None of the above

Explanation: Dan and Guy are siblings. However, we do not know whether they are full siblings or half brothers. Margaret, Guy’s mother, might not be Dan’s mother. Joshua, who is Dan’s father, might not be Guy’s father.

Thus, the answer is D.

Q. If there are no dancers that aren’t slim and no singers that aren’t dancers, then which statements are always true?

  1. There is not one slim person that isn’t a dancer
  2. All singers are slim
  3. Anybody slim is also a singer
  4. None of the above


The tricky part here is that the question is phrased negatively. This means that we first of all need to identify the nature of each group. Then, we establish the relationship between the groups. If we draw ourselves a diagram (as in the example above), the relationship between the groups becomes clearer. The only true statement is that all singers are slim.

Thus, The answer is B.
