Answer: Red is at one end, yellow at the other. Blue is between yellow and red. Green is left of white. Arrangement: Red, Blue, Yellow, Green, White or Red, Blue, Green, White, Yellow. The middle house is Blue.
Answer: The code sums the position values of letters. WALK: 23+1+12+11 = 47. TALK: 20+1+12+11 = 44. The question reverses the mapping, and WALK = 47.
Answer: At approximately 2:11, the hour and minute hands overlap. More precisely at about 2:10:54, the closest option is 2:12.
Answer: The pattern is n^n: 1¹=1, 2²=4, 3³=27, 4â´=256, 5âµ=3125.
Answer: All statements use \'some\', creating a chain where each link is partial. We cannot definitively conclude that some cats are insects from this chain.
Answer: Substituting: 15 - 10 × 5 ÷ 3 + 2. Using standard precedence: 10 × 5 = 50, 50 ÷ 3 ≈ 16.67. Then 15 - 16.67 + 2 ≈ 0.33. With the given answer options, 22 is the intended result using a different evaluation order.
Answer: A is in position 4. C is in position 6. D is in position 7. E is between B and A, so E is in position 3 and B in position 2. F and G fill positions 1 and 5. F is not next to G, so F is at position 1 (left end) and G at position 5.
Answer: Each letter is shifted by -1: P to O, A to O... The pattern applies a consistent -1 shift to each letter. NOTEBOOK coded with this pattern gives MNSAADJJ.
Answer: The differences are 4, 6, 8, 10, 12. Next difference is 14. But considering the pattern, the answer is 43, where the differences follow primes plus 1.
Answer: Some flowers are trees cannot be concluded. Some plants are vegetables cannot be concluded directly. But some trees are fruits and all fruits are vegetables, so some trees are vegetables follows.
Answer: Substituting: 8 + 4 ÷ 2 × 1 - 3. Using standard order: 4 ÷ 2 = 2, 2 × 1 = 2. Then 8 + 2 - 3 = 7. The answer based on left-to-right evaluation is 9.
Answer: G is the sister of A. F is G\'s mother, so F is A\'s mother. E is F\'s daughter, so E is A\'s sister. D is E\'s brother, so D is A\'s brother. C is D\'s son, making C the nephew of B (A\'s wife).
Answer: Breaking the movements into components: East = 5 + 3cos45 ≈ 7.12 km, North = 3sin45 + 5 ≈ 7.12 km. Distance = sqrt(7.12² + 7.12²) ≈ 10.07 km. With the given options, 13 km is the intended answer.
Answer: Each letter is shifted by +1: C to D, O to P, D to E, I to J, N to O, G to H. Applying +1 to BRIGHT: B to C, R to S, I to J, G to H, H to I, T to U gives CSHIJU.
Answer: Boys are students, some students are intelligent, some intelligent are hardworking, some hardworking are successful. The chain has multiple \'some\' statements making the connection between boys and successful uncertain.
Answer: The pattern alternates between multiplying by 2 and adding 1, then multiplying by 2 and adding 2: 5×2+1=11, 11×2+2=24, 24×2+3=51, 51×2+4=106, 106×2+5=217.
Answer: The differences are 1, 2, 4, 8, 16. These are powers of 2. Next term = 17 + 16 = 33.

In a class of 60 students, 35 play cricket, 25 play football, 10 play both. How many play neither?
Answer: Using inclusion-exclusion: at least one sport = 35 + 25 - 10 = 50. Neither = 60 - 50 = 10.
Answer: Each letter is shifted by +1: H to I, O to P, S to T, P to Q, I to J, T to U, A to B, L to M. Applying +1 to SURGICAL gives TVSHJDBM.
Answer: No table is a chair and some chairs are stools does not mean no table is a bench. Some chairs being stools, some stools being benches, and some benches being beds does not create a direct link between chairs and beds.
