Q.1. Mr. Ugach went 20 Km towards south and took right turn traveling 40 Km. Again he took right traveling 20 Km. Finally, he turned left traveling 30 Km. How far and in which direction is he from the starting point ?


Graphical Ans of Q.1 from Direction sense

In given image just imagine that you are going on that path and turns as directed in question. SHORTCUT for above question: Subtract opposite terms and add Like terms.
S   W  N  W
20 40 20 30
So, After removing S-N = 0 and adding W+W = 70 Km towards West
Here, Just subtract opposite directions and add the same directions i.e. If you are going 10 km North and again 10 km to South in same direction you’ll end up at same position so we can directly subtract N with S and vice versa.
