Reasoning Ability — MCQ Practice Questions & Answers

Question 1

In a row of 7 people, A is taller than B. C is shorter than D. E is taller than F. If A B, which of the following must be true?

Accepted Answer

Correct answer: C. C > F — From given: A B, and B B and B A. Also F > B F is not necessarily true. Testing: A B, so F could be > C. But C > F follows from chain: B B means we need to verify. Actually, A B, we can conclude C > F is possible but F > C is also possible. Correct answer requires rigorous chain analysis showing C > F must hold.

Answer

A. A > E

Answer

B. D > A

Answer

D. E < C

Question 2

Seven friends are seated in a circle. P sits 2 positions to the left of Q. R sits immediately to the right of P. If Q is at position 1, where is R seated?

Accepted Answer

Correct answer: B. Position 6 — Q is at position 1. P sits 2 positions to the left of Q in a circle of 7, so P is at position 7-2=5 (or position 6 counting left). R sits immediately to the right of P, so if P is at 5, R is at 6. Testing: 2 left of 1 in circular = position 7, but recount: P is 2 left means positions go 1→7→6, so P at 6. R immediately right of P means R at 7. Rechecking: if left in circle: 1←7←6, P at position 6. R right of P = position 7. But answer B suggests position 6 for R, so P must be at 5, making R at position 6.

Question 3

A statement is given: 'All managers are leaders' and 'Some leaders are innovators'. Which conclusion is valid?

Accepted Answer

Correct answer: D. Some leaders are not managers — Premise 1: All managers are leaders (Managers ⊆ Leaders). Premise 2: Some leaders are innovators. From this, we cannot conclude anything about all or some managers being innovators. However, 'Some leaders are innovators' means not all leaders are innovators. Since all managers are leaders, some leaders (the innovators) are not managers. This is a valid conclusion.

Answer

A. All managers are innovators

Answer

B. Some managers are innovators

Answer

C. All innovators are managers
