IBPS Syllogism and Logical Reasoning 4 — Questions and Answers
Question 1: Statements: All rivers are oceans. Some oceans are seas. Conclusions: I. Some rivers are seas. II. Some seas are oceans. Which conclusion(s) follow?
- Only I follows
- Only II follows (Correct answer)
- Both I and II follow
- Neither I nor II follows
Correct answer: Only II follows
There is no direct link between rivers and seas; converting 'some oceans are seas' gives 'some seas are oceans.'
Question 2: A is taller than B. C is shorter than D. D is taller than A. Who is the tallest?
- A
- B
- C
- D (Correct answer)
Correct answer: D
D > A > B and D > C, so D is the tallest among all.
Question 3: Statements: Some coins are notes. All notes are currency. Conclusions: I. All coins are currency. II. Some currency are coins. Which conclusion(s) follow?
- Only I follows
- Only II follows (Correct answer)
- Both I and II follow
- Neither I nor II follows
Correct answer: Only II follows
Only some coins are notes, so we cannot say all coins are currency; from 'some coins are notes' and 'all notes are currency,' some coins are currency, converting to some currency are coins.
Question 4: Six people A, B, C, D, E, F sit in a circle facing the centre. B sits between A and C. D sits opposite B. Who sits opposite A?
- D
- E (Correct answer)
- F
- C
Correct answer: E
With B between A and C and D opposite B, the remaining seats for E and F place E opposite A in a symmetric circular arrangement.
Question 5: Statements: No star is a planet. All planets are celestial bodies. Conclusions: I. No star is a celestial body. II. Some celestial bodies are not stars. Which conclusion(s) follow?
- Only I follows
- Only II follows (Correct answer)
- Both I and II follow
- Neither I nor II follows
Correct answer: Only II follows
Stars could be celestial bodies through other links, so Conclusion I is too strong; but since planets (a subset of celestial bodies) are not stars, some celestial bodies are not stars.
Question 6: If MANGO is coded as 13-1-14-7-15, how is GRAPE coded?
- 7-18-1-16-5 (Correct answer)
- 7-17-1-15-4
- 8-18-1-16-5
- 6-18-1-16-5
Correct answer: 7-18-1-16-5
Each letter is replaced by its position in the alphabet: G=7, R=18, A=1, P=16, E=5.
Question 7: Statements: Some chairs are tables. Some tables are desks. Conclusions: I. Some chairs are desks. II. No desk is a chair. Which conclusion(s) follow?
- Only I follows
- Only II follows
- Both I and II follow
- Neither I nor II follows (Correct answer)
Correct answer: Neither I nor II follows
Two particular affirmative statements yield no definite conclusion; neither I nor II can be confirmed.
