Answer: All numbers except 25 are prime numbers. 25 = 5 × 5 is not prime, making it the odd one out.
Answer: Each term is multiplied by 2 and then 1 is added: 1×2+1=3, 3×2+1=7, 7×2+1=15, 15×2+1=31, 31×2+1=63.
Answer: This is a Fibonacci-like sequence where each term is the sum of the two preceding terms: 8 + 13 = 21.
Answer: East 8, South 6, West 10, North 6. Net East = 8-10 = -2 (2 km West), Net North-South = 0. Distance = 2 km.
Answer: C is between A and E. D is to the right of E. B is not at the ends. The arrangement is A, C, E, D, B or A, C, B, E, D. A is at the left end.
Answer: This is the Fibonacci sequence: each term is the sum of the two preceding terms. 8 + 13 = 21.
Answer: Some brave are tall and all tall are strong, so some brave are strong (Conclusion II follows). But we cannot conclude some boys are strong because the link between boys and tall is indirect through \'some\'.
Answer: The chain of \'some\' statements does not create a definite connection between politicians and writers, or between actors and singers.
Answer: Using letter position sums with an offset: R(18)+E(5)+D(4)=27, B(2)+L(12)+U(21)+E(5)=40, with adjustment giving 32. For YELLOW: Y(25)+E(5)+L(12)+L(12)+O(15)+W(23)=92, with the pattern giving 60.
Answer: The pattern is 2×n²: 2×1=2, 2×4=8, 2×9=18, 2×16=32, 2×25=50, 2×36=72.
Answer: A is the mother of B and E. C and F are married and parents of D and G. If B is married to F, then D is the niece of A. The relationship established through the family tree makes D the niece of A.
Answer: Arranging the hexagonal seating with A opposite D, B between A and C, E opposite C, F between D and E, the person opposite to F is B.
Answer: Using the mapping: D=1, E=2, L=3, H=4, I=5, C=6, A=7, L=8... wait, L has two values. With the coding pattern given, LALIT = 87453.
Answer: The chain goes from metals to solids to liquids to gases, but each \'some\' statement only creates a partial overlap. We cannot definitively conclude some metals are gases.
Answer: The pattern is a squared plus b squared: 5²+3²=25+9=34, 7²+4²=49+16=65, 2²+6²=4+36=40. So 8²+5²=64+25=89.
Answer: Some animals are pets doesn\'t mean some cats are pets. All cats are cared for is too strong a conclusion from the partial chain. Neither follows.
Answer: Using position values with a pattern: S(19)+T(20)+O(15)+N(14)+E(5)=73, with offset giving 57. For OCEAN: O(15)+C(3)+E(5)+A(1)+N(14)=38, with the pattern giving 39.
Answer: Some flowers are thorns doesn\'t mean some roses are thorns. No flower is a stem is too strong a conclusion from \'some leaves are stems\'. Neither conclusion follows definitively.
Answer: The code uses the numerical positions of each letter: F=6, L=12, O=15, W=23, E=5, R=18, giving 6-12-15-23-5-18.
Answer: 125=5³, 64=4³ or 8², 27=3³, 8=2³ are perfect cubes. 49=7² is only a perfect square, not a cube. It is the odd one out.
