Meghna starts at A, walks 7 m West, turns left and walks 2 m to C, turns right and walks 4 m to D, turns right and walks 2 m, then turns right and walks 3 m to B. How far and in which direction is A from B?

1. Take A = (0,0). West 7 m → (−7,0); left (south) 2 m → C(−7,−2). 2. Right (west) 4 m → D(−11,−2); right (north) 2 m → (−11,0); right (east) 3 m → B(−8,0). 3. A(0,0) is 8 m east of B(−8,0). So A is **8 m towards East** of B. _Source: IBPS RRB Officer Scale I Prelims PYQ (Examrace), Q.34_
