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: 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: 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: 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.

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: 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: 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: 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: 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: 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: The differences are 1, 2, 4, 8, 16. These are powers of 2. Next term = 17 + 16 = 33.
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: 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: 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.
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: 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: 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 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.
