Radha moves towards South-East a distance of 7 km, then she moves towards West and travels a distance of 14 km. From here she moves towards North-West a distance of 7 km and finally she moves a distance of 4 km towards east. How far is she now from the starting point?

A. 3 km B. 4 km
C. 10 km D. 11 km

• ----- LOGIC BEHIND -----
  The basic logic behind solving this type of Q's are
  1. Add all distances which are in same direction, then
  2. Subtract it with the opposite one.
  ----- Answer ----
  Total distance towards S-E = 7km
  Total distance towards N-W (Opposite to S-E)= 7km
  So, subtract S-E dist. with N-W dist.(d1)= 0km
  
  Now Total distance towards W = 14km
  Total distance towards E = 4km
  So, subtract W to E (d2)= 10km
  
  At last add up all the dist. (i.e d1 and d2) = 10+0 km = 10km (C).
