A man starts from a point A and walks 30 metres towards the south. From there he turns left and walks 40 metres. Again he turns left and walks 30 metres and reaches a point B. How far and in which direction is the man now from point A?
A20 metres West
B30 metres East ✓ Correct
C20 metres North
D20 metres South
Correct answer: (B) 30 metres East
Explanation
Point B lies to the east of A.
From A: 30 m south, then a left turn faces east.
Walk 40 m east, then a left turn faces north.
Walk 30 m north, cancelling the earlier 30 m south.
Only the eastward leg remains, so B is due east of A.
