Amit runs 30m towards the North and turns right. Then he runs 20m and turns to right, runs 10m and turns left. Then he runs 8m and turns right. After running 15m, he finally turns left and runs 5m. Now which direction is Amit facing?

A)  North                          

B)  West

C)  South              

D)  East

Correct Answer: D

Shortcut: One right-turn cancels one left-turn. North + 2 Right Turns = South North \[+R+\cancel{R}+\cancel{L}+\cancel{R}+\cancel{L}\] = North + Right = East
