CMAT Logical Reasoning 5 ā Questions and Answers
Question 1: In a sequence of letters AZBYCX_W, what letter fills the blank?
- D (Correct answer)
- V
- E
- U
Correct answer: D
The pattern alternates forward (A,B,C,Dā¦) and backward (Z,Y,X,Wā¦) sequences; the missing letter is D.
Question 2: Some books are pens. Some pens are erasers. Which conclusion follows?
- Some books are erasers
- No book is an eraser
- Some erasers are books
- None of the above necessarily follows (Correct answer)
Correct answer: None of the above necessarily follows
Both 'some books are pens' and 'some pens are erasers' do not guarantee any direct link between books and erasers.
Question 3: If 5 + 3 = 28, 9 + 1 = 810, 8 + 6 = 214, then 7 + 3 = ?
- 410 (Correct answer)
- 44
- 710
- 47
Correct answer: 410
The pattern is (aāb)(a+b): 5+3ā(2)(8)=28, 9+1ā(8)(10)=810, 8+6ā(2)(14)=214, so 7+3ā(4)(10)=410.
Question 4: Arrange the following in logical sequence: 1. Sentence 2. Letter 3. Word 4. Paragraph 5. Chapter
- 2,3,1,4,5 (Correct answer)
- 3,2,1,4,5
- 2,1,3,4,5
- 1,2,3,4,5
Correct answer: 2,3,1,4,5
The correct order from smallest to largest unit is: Letter ā Word ā Sentence ā Paragraph ā Chapter.
Question 5: Which figure completes the matrix? In a 3Ć3 grid, rows contain circle, square, triangle in some order, each row uses all three shapes. Row 1: circle, square, triangle. Row 2: triangle, circle, square. Row 3: square, ?, circle.

Correct answer: Triangle
Each shape appears exactly once per row and column; the missing shape in row 3 position 2 must be triangle.
Question 6: A is heavier than B, C is lighter than A, D is heavier than A but lighter than E. Who is the heaviest?
- E (Correct answer)
- D
- A
- B
Correct answer: E
The order is E > D > A > C and A > B, so E is the heaviest overall.

- All untrusted people are dishonest (Correct answer)
