In a square arrangement,let the initial positions be $A$ (North-West),$B$ (North-East),$C$ (South-East),and $D$ (South-West). $C$ and $A$ move diagonally to opposite corners and then one side each clockwise and anticlockwise respectively. $B$ and $D$ move two sides each clockwise and anticlockwise respectively. Who is at the North-West corner?

Point $B$ is $12 \,meters$ south of point $A.$ Point $C$ is $24 \,meters$ east of point $B.$ Point $D$ is $8 \,meters$ south of point $C.$ Point $D$ is $12 \,meters$ east of point $E$ and point $F$ is $8 \,meters$ north of point $E.$ If a man has to travel to point $E$ from point $A$ (through these points by the shortest distance),which of the following points will he pass through first?

$A$ man is facing south. He turns $135^{\circ}$ in the anticlockwise direction and then $180^{\circ}$ in the clockwise direction. Which direction is he facing now?

In a row of children facing north,Manish is fourth to the left of Suresh,who is tenth from the left end. Nisha is second to the right of Suresh and eighth from the right end of the row. Total how many children are there in the row?

Kashish goes $30 \, m$ North,then turns right and walks $40 \, m$,then again turns right and walks $20 \, m$,then again turns right and walks $40 \, m$. How many metres is he from his original position?

Gaurav walks $20 \, m$ towards North. He then turns left and walks $40 \, m$. He again turns left and walks $20 \, m$. Further,he moves $20 \, m$ after turning to the right. How far is he from his original position (in $, m$)?
