A) 10                  

B)        24

C) 28                       

D)       38

E) None of these

Correct Answer: B

Solution :

Explanation Option [b] is correct. Let us see: The movements of the person are given mentioned as in figure. [A to B, B to C, C to D and D to E] Clearly, the final position is F. Which is to North-East of the starting point A. \[\to \,\,AE=\,(AB\,+BE)\] \[\to \,AE=\,(AB\,+CD)\] \[\to \,\,AE=\,(14+10)m\] \[\to \,\,AE=24m.\]
