9=3², 16=4², 25=5² (consecutive perfect squares). Similarly, 25=5², 36=6², 49=7² maintains the same relationship of consecutive perfect squares.
From 'some Cats are Dogs' and 'some Dogs are Pigs', we cannot conclude that 'some Cats are Pigs' or 'some Pigs are Cats'. The overlap is insufficient.
North 6 km, East 8 km, South 6 km. Net displacement: 8 km East, 0 km North-South. Distance from start = 8 km
Pattern: 1×2=2, 2×3=6, 3×4=12, 4×5=20, 5×6=30, 6×7=42
The code represents the number of letters. CAT=3 letters, DOG=3 letters, ELEPHANT=8 letters. RABBIT=6 letters.
Each letter is shifted by +1 position. P→Q, E→F, N→O, C→D, I→J, L→M. Similarly, S→T, C→D, I→J, E→F, N→O, C→D, E→F gives TDGJOCF. Check: SCIENCE = TDGMSHF (each letter +1)
Series of perfect squares: 1², 2², 3², 4², 5², 6² = 36
E is wife of D, so E is mother of C. A is daughter of B. If B is child of D and E, then A is granddaughter of E. Needs clarification - A is niece of C if B is sibling of C.
Position from left = 12, Position from right = 8. Total = 12 + 8 - 1 = 19
The pattern alternates between empty square and filled square. After □, the next should be ■, then □, then ■.
