Solution

The correct option is A 2 km west
Clearly Johnson drove 15 km from A to B north wards
and then 10 km from B to C towards west He then
moves 5 km southwards from C to D and 8 km east-
wards upto E Finally he turned right and moved 10 km upto F
A and F lie in the same straight line and F lies to the west of A
So Johnson's distance from the starting point
A = AF = (BC - DE) = (10 - 8)km = 2km.
