Total students = 10. Position from right = Total - Position from left + 1 = 10 - 5 + 1 = 6

Mother's daughter = Priya. So the man's mother is Priya, making him Priya's son.

This follows the logical chain from general to specific, which is deductive reasoning (syllogism).

Each letter is replaced by its position in the alphabet. L=12, O=15, O=15, K=11.

Differences are 3, 5, 7, 9, 11. Pattern is n² + 1. Next: 6² + 1 = 37

A sword is a tool used by a warrior. Similarly, a pen is a tool used by a writer.

He ends up 5 km east of his starting position. Net displacement = 5 km

This is the Fibonacci sequence where each number is the sum of the previous two. 13 + 8 = 21

If Priya is 6th from left in a row of 10, then from right = 10 - 6 + 1 = 5th

Net displacement: North 5-5=0, East 3. Final position is 3 km east of start
