Ravi's mother's father = Ravi's grandfather. His son = Ravi's uncle. His daughter = Ravi's cousin.

These are perfect squares: 1²=1, 2²=4, 3²=9, 4²=16, 5²=25, 6²=36, 7²=49, 8²=64.

While all dogs are animals, cats could be or not be animals based on the premises. The first statement only tells us cats aren't dogs, not about their relationship with animals.

Each letter is coded by its position in the alphabet. P=16, A=1, P=16, E=5, R=18. So PAPER = 16-1-16-5-18.

B right of A: A-B. C left of D: C-D. E between C and D: C-E-D. D right of B: combining gives A-B-C-E-D.

The analogy reverses the spelling. FLOWER reversed = REWOLF. GARDEN reversed = NEDRAG.

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.
