ICET Logical Reasoning 1 — Questions and Answers
Question 1: What is the next number in the series: 2, 6, 12, 20, 30, ?
- 40
- 42 (Correct answer)
- 44
- 36
Correct answer: 42
The differences between consecutive terms are 4, 6, 8, 10, 12 (increasing by 2 each time), so the next term is 30 + 12 = 42.
Question 2: Find the next term in the letter series: A, C, F, J, O, ?
- S
- T
- U (Correct answer)
- V
Correct answer: U
The gaps between letters increase by 1 each time (2, 3, 4, 5, 6), so the next letter is O + 6 positions = U.
Question 3: BOOK is to LIBRARY as PAINTING is to ___.
- Canvas
- Museum (Correct answer)
- Artist
- Frame
Correct answer: Museum
Just as a book is stored and displayed in a library, a painting is stored and displayed in a museum.
Question 4: Which number does NOT belong in the group: 2, 3, 5, 7, 9, 11?
- 2
- 5
- 9 (Correct answer)
- 11
Correct answer: 9
9 = 3 × 3, making it a composite number, while 2, 3, 5, 7, and 11 are all prime numbers.
Question 5: A is the brother of B. B is the sister of C. C is the father of D. How is A related to D?
- Father
- Uncle (Correct answer)
- Grandfather
- Brother
Correct answer: Uncle
A and B are siblings, B and C are siblings, so A and C are siblings; since C is D's father, A (a male sibling of D's father) is D's uncle.
Question 6: A man walks 10 km north, then 6 km east, then 10 km south. How far is he from his starting point?
- 4 km
- 6 km (Correct answer)
- 10 km
- 16 km
Correct answer: 6 km
The 10 km north and 10 km south cancel each other out, leaving him only 6 km east of his starting point.
Question 7: In a code language, APPLE is written as BQQMF. How is GRAPE written in that language?
- HSBQF (Correct answer)
- ITBQG
- GSBQF
- HSCQF
Correct answer: HSBQF
Each letter is shifted forward by 1 position in the alphabet (A→B, P→Q, P→Q, L→M, E→F), so G→H, R→S, A→B, P→Q, E→F gives HSBQF.
