A → C

C → E

K → M

Explanation

Start at point O.

1. Walk 10 m north  

2. Walk 15 m east  

3. Walk 10 m south  

Net movement north-south: 10 m north - 10 m south = 0 m  

Net movement east-west: 15 m east  

So final position is 15 m east of the starting point.  

He is in the East direction from the starting point.

Explanation

P is the son of Q.  

Q is the sister of R.  

R is the father of the man.  

So:  

R is the father of the man → The man is R's son.  

Q is R's sister → Q is the man's aunt.  

P is Q's son → P is the son of the man's aunt.  

Son of aunt = Cousin.  

So the man is the Cousin of P.
