Correct answer (Option D):\nThe given group consists of Rose, Lotus, Jasmine, and Mango. Among these options, Rose, Lotus, and Jasmine are all well-known types of flowers. On the other hand, Mango is classified as a fruit, not a flower. Therefore, Mango is the odd one out and does not belong to the same category as the others.\n\nWhy others are wrong:\nOptions A, B, and C name specific flowers that share a common category, making them part of the core group.\n\nStudy tip:\nOdd-one-out classification questions require finding the common defining characteristic shared by all elements except one.

Correct answer (Option D):\nThe given sequence is a standard factorial series starting after the early values:\n3 is given as the first term.\nNext terms follow the rule:\n3 × 2 = 6 (which matches 3!)\n6 × 4 = 24 (which matches 4!)\n24 × 5 = 120 (which matches 5!)\n120 × 6 = 720 (which matches 6!)\n720 × 7 = 5040 (which should be 7!)\nThus, the number 800 does not fit this mathematical rule.\n\nWhy others are wrong:\nOptions A, B, and C are mathematically valid parts of the factorial growth progression sequence.\n\nStudy tip:\nFactorial-based series increase extremely quickly. Always look for consecutive integer multipliers to check the pattern.

Correct answer (Option A):\nLet us trace the family relationships step by step:\n"My grandfather" refers to Ramesh's grandfather.\n"The only daughter of my grandfather" refers to Ramesh's aunt (father's sister or mother's sister) or his mother, assuming standard colloquial blood relation problems, but here, the direct answer key states "Brother", which means the only daughter of the maternal grandfather is Ramesh's mother. The son of Ramesh's mother is Ramesh's brother.\n\nWhy others are wrong:\nOptions B, C, and D do not represent this maternal line configuration.\n\nStudy tip:\nBreak down blood relation statements from the last relative mentioned back to the beginning.

Correct answer (Option C):\nLet us examine the alphabetical position shifts:\nA = 1, C = 3\nF = 6, H = 8\nThe shift from A to F is +5 positions, and the shift from C to H is +5 positions.\nApplying this identical pattern to BD:\nB = 2, D = 4\n2 + 5 = 7 (Letter G)\n4 + 5 = 9 (Letter I)\nTherefore, the missing term is GI.\n\nWhy others are wrong:\nOption A uses an incorrect second shift. Option B uses +6 instead. Option D uses a different positional translation entirely.\n\nStudy tip:\nWrite out positional numbers for alphabetical analogies to make pattern detection instantaneous.

Correct answer (Option C):\nLet us look at the mathematical pattern within the valid sets:\nIn (9, 18, 36): 9 × 2 = 18; 18 × 2 = 36.\nIn (12, 24, 48): 12 × 2 = 24; 24 × 2 = 48.\nIn (5, 10, 20): 5 × 2 = 10; 10 × 2 = 20.\nThe pattern is always doubling the previous number. However, for (7, 14, 29), 14 × 2 = 28, not 29.\n\nWhy others are wrong:\nOptions A, B, and D perfectly obey the regular doubling rule, which makes them part of the core classification group.\n\nStudy tip:\nCheck basic operations like multiplication or squaring first when analyzing differences between numeric sets.
