The premises don't establish a direct relationship between triangles and rectangles. While all triangles are polygons and some polygons are rectangles, we cannot conclude about the intersection of triangles and rectangles.
Pattern: Each term = 2 × previous term + 1. 2→5(2×2+1), 5→12(2×5+2), 12→27(2×12+3), 27→58(2×27+4), 58→121(2×58+5), 121→246(2×121+4).
Starting North-East (45°). Turn 135° clockwise: 45° + 135° = 180° (South). Turn 45° counter-clockwise: 180° - 45° = 135° (South-East), which simplifies to East direction.
Mother's only son = the man himself. His son's wife = his daughter-in-law. His daughter-in-law's daughter = his granddaughter or in simpler terms, his daughter through relation. Actually, it's his daughter directly.
The code uses position of letters in the alphabet. S=19, C=3, I=9, E=5, N=14, C=3, E=5. Therefore SCIENCE = 19-3-9-5-14-3-5.
Using circular arrangement logic: A's position is fixed. D is 2nd to left (clockwise from A's perspective). B is 3rd to right. E between C and F helps determine the remaining positions. C sits to immediate right of G.
North=0°, East=90°, South=180°, West=270°. Southwest is between South and West = 225° (clockwise from North).
Dogs are mammals. Some pets are birds. This implies remaining pets could be mammals. Therefore, some pets are mammals (valid).
Woman's son's mother = Woman. Woman's mother's husband = Woman's father. No wait: son's mother = woman. Woman's husband = husband.
Each number is multiplied by 2. 12×2=24, 24×2=48, 48×2=96, 96×2=192, 192×2=384.
