• none of these
• 11 years agoHelpfull: Yes(1) No(0)
• answer is 14
• 10 years agoHelpfull: Yes(1) No(2)
• 10 is the right answer...
  
• 10 years agoHelpfull: Yes(1) No(0)
• none of these...
  answer is 10 km

• 14 km. Option D. (Distance is asked not Displacement)
  As she goes west 10 km. then left and 8 km and then again 4 km left which implies that she retrace her path again, so on deducting 4 from 10 i.e 6 and adding the vertical 8 km gives us the total distance she covered from her office.

  we have find distance ae
  so ae^2=ab^2+be^2

• 14KM
  W10,S8,E4
  so we can subtract opposite directions
  W10-E4=W6
  W6+S8=14KM
• 10 years agoHelpfull: Yes(0) No(2)
• (12-4)km=8km
• 10 years agoHelpfull: Yes(0) No(0)
• From directional rules ans will be 10km. thus none of these.

• solution:14 km

• 10-4=6 km(West)so ans is E
  
  First she moves 10 km towards west & at that point she turns left i.e towards south & walks 8 km then she again turns to her left i.e towards south-east & walks 4 km now finally she is 6 km west from her office
  so,ans is E.
• 10 years agoHelpfull: Yes(0) No(0)
• 10km at south west As like (10-4)^2+8^2=10^2
  So answer is:e
• 10 years agoHelpfull: Yes(0) No(0)
• (10-4)^2+8^2=d^2, where d=distance of current position from office
  =>d=10.
• 10 years agoHelpfull: Yes(0) No(0)
• 10km towards west from her office, then
  8km towards from her left then 4 from her left, that makes
  10-4=6 and then,
  6+8=14km ans....
  
• 10 years agoHelpfull: Yes(0) No(0)
• The Correct option is E.
  Correct answer is 10km.

  in the end a right triangle is formed with hypotenuse being the answer.
