RRB Technician Grade 3 Reasoning: Reasoning is one of the most important sections in the RRB Technician Exam. In this section, the board evaluates the logical thinking and problem-solving skills of a candidate. In this article. We have provided some mock questions for RRB Technician Grade 3 Reasoning. Candidates will get an idea about the difficulty level of the reasoning section from these mock questions.
Analogy
Question: Book is to Author as Painting is to:
a) Canvas
b) Brush
c) Artist
d) Gallery
Answer: c) Artist
Explanation: The relationship between a book and an author is that an author creates a book. Similarly, an artist creates a painting. Therefore, the correct analogy is “Painting is to Artist”.
Series Completion
Question: Find the missing number in the series:
2, 6, 12, 20, ?, 42
a) 30
b) 32
c) 28
d) 36
Answer: a) 30
Explanation: The pattern in this series is that each number is obtained by adding consecutive odd numbers:
2 + 4 = 6
6 + 6 = 12
12 + 8 = 20
20 + 10 = 30
30 + 12 = 42
Therefore, the missing number is 30.
Direction Sense
Question: Rahul walks 5 km towards North, then turns left and walks 3 km. He then turns right and walks 2 km. Finally, he turns right again and walks 3 km. How far is he from his starting point?
a) 5 km
b) 7 km
c) 8 km
d) 10 km
Answer: b) 7 km
Explanation: Let’s break this down step by step:
- Rahul walks 5 km North
- Then 3 km West
- Then 2 km North
- Finally 3 km East
The 3 km East cancels out the 3 km West. So effectively, Rahul has moved:
- 7 km North (5 km + 2 km)
- 0 km East/West
Therefore, he is 7 km away from his starting point.
Logical Venn Diagrams
Question: In a class of 50 students, 30 like Mathematics, 25 like Physics, and 20 like both Mathematics and Physics. How many students like neither Mathematics nor Physics?
a) 15
b) 20
c) 25
d) 10
Answer: a) 15
Explanation: Let’s solve this step by step:
- Total students = 50
- Students who like both Math and Physics = 20
- Students who like only Math = 30 – 20 = 10
- Students who like only Physics = 25 – 20 = 5
- Students who like either Math or Physics or both = 20 + 10 + 5 = 35
- Students who like neither = Total students – Students who like either = 50 – 35 = 15
Therefore, 15 students like neither Mathematics nor Physics.
Coding-Decoding
Question: If ROAD is coded as URDG, then how will SWAN be coded?
a) VZDQ
b) VZDP
c) UXDP
d) UXDQ
Answer: a) VZDQ
Explanation: In the given code, each letter is replaced by the letter that comes three positions after it in the alphabet:
R → U (3 positions after R)
O → R (3 positions after O)
A → D (3 positions after A)
D → G (3 positions after D)
Applying the same logic to SWAN:
S → V (3 positions after S)
W → Z (3 positions after W)
A → D (3 positions after A)
N → Q (3 positions after N)
Therefore, SWAN will be coded as VZDQ.
Blood Relations
Question: A is the father of B. C is the son of B. D is the brother of B. How is D related to C?
a) Father
b) Uncle
c) Brother
d) Grandfather
Answer: b) Uncle
Explanation: Let’s break down the relationships:
- A is B’s father
- B is C’s father (as C is B’s son)
- D is B’s brother
Since D is B’s brother and C is B’s son, D is C’s uncle.
Syllogism
Question:
Statement 1: All cats are animals.
Statement 2: Some animals are pets.
Conclusion: Some cats are pets.
Is the conclusion logically correct?
a) Yes
b) No
c) Cannot be determined
d) None of the above
Answer: c) Cannot be determined
Explanation: The given statements tell us that:
- All cats belong to the set of animals.
- Some animals belong to the set of pets.
However, we don’t know if the animals that are pets include any cats. All pets may be animals other than cats. Therefore, based on the given information, we cannot determine whether some cats are pets or not.
Number Series
Question: Which number would replace the question mark in this series?
3, 7, 13, 21, 31, ?
a) 43
b) 41
c) 45
d) 39
Answer: a) 43
Explanation: The pattern in this series is that the difference between consecutive terms increases by 2 each time:
3 to 7: difference of 4
7 to 13: difference of 6
13 to 21: difference of 8
21 to 31: difference of 10
31 to ?: difference should be 12
So, 31 + 12 = 43
Odd One Out
Question: Which word does not belong with the others?
a) Lion
b) Tiger
c) Leopard
d) Elephant
Answer: d) Elephant
Explanation: Lion, Tiger, and Leopard are all big cats belonging to the Felidae family. Elephant, on the other hand, belongs to the Elephantidae family and is not a cat. Therefore, Elephant is the odd one out in this group.
Logical Deduction
Question: In a row of children, Ravi is 7th from the left and 4th from the right. How many children are there in the row?
a) 9
b) 10
c) 11
d) 12
Answer: b) 10
Explanation: Let’s approach this step-by-step:
- Ravi is 7th from the left, meaning there are 6 children to his left.
- Ravi is 4th from the right, meaning there are 3 children to his right.
- To get the total number of children, we add:
- Children to Ravi’s left (6)
- Ravi himself (1)
- Children to Ravi’s right (3) 6 + 1 + 3 = 10
Therefore, there are 10 children in the row.
