GAT Logical Reasoning 2 — Questions and Answers
Question 1: Five friends sit in a row. Ahmad is to the left of Khalid. Omar is between Ahmad and Khalid. Fahad is at the far right. Yusuf is to the left of Ahmad. What is the order from left to right?
- Yusuf, Ahmad, Omar, Khalid, Fahad (Correct answer)
- Ahmad, Yusuf, Omar, Khalid, Fahad
- Yusuf, Omar, Ahmad, Khalid, Fahad
- Fahad, Khalid, Omar, Ahmad, Yusuf
Correct answer: Yusuf, Ahmad, Omar, Khalid, Fahad
From the clues: Yusuf is left of Ahmad, Ahmad is left of Khalid, Omar is between Ahmad and Khalid, and Fahad is far right. This gives: Yusuf, Ahmad, Omar, Khalid, Fahad.
Question 2: Which number should replace the question mark? 4, 9, 16, 25, ?
- 30
- 36 (Correct answer)
- 49
- 32
Correct answer: 36
These are perfect squares: 2²=4, 3²=9, 4²=16, 5²=25, 6²=36. The next number is 36. Recognizing square numbers is important for Qudurat pattern questions.
Question 3: In a group of 30 Saudi students, 18 study math, 15 study science, and 5 study both. How many study neither?
- 0
- 2 (Correct answer)
- 5
- 7
Correct answer: 2
Using inclusion-exclusion: Students in at least one = 18 + 15 - 5 = 28. Students in neither = 30 - 28 = 2. This is a classic set theory problem.
Question 4: A clock shows 3:15. What is the angle between the hour and minute hands?
- 0°
- 7.5° (Correct answer)
- 15°
- 90°
Correct answer: 7.5°
At 3:15, the minute hand points at 3 (90°). The hour hand has moved past 3 by 15 minutes × 0.5°/min = 7.5°. So it's at 97.5°. The angle between them = 97.5° - 90° = 7.5°.
Question 5: If SAUDI is coded as TBVEJ using a simple letter shift, how would RIYADH be coded?
- SJZBEI (Correct answer)
- QHXZCG
- SJZAEI
- TKZAEI
Correct answer: SJZBEI
S→T (+1), A→B (+1), U→V (+1), D→E (+1), I→J (+1). Each letter shifts forward by 1. Applying to RIYADH: R→S, I→J, Y→Z, A→B, D→E, H→I = SJZBEI.
Question 6: A farmer has chickens and goats. He counts 20 heads and 56 legs. How many goats does he have?
- 6
- 8 (Correct answer)
- 10
- 12
Correct answer: 8
Let g = goats, c = chickens. Heads: g + c = 20. Legs: 4g + 2c = 56. From equation 1: c = 20 - g. Substituting: 4g + 2(20-g) = 56 → 4g + 40 - 2g = 56 → 2g = 16 → g = 8.
