One morning after sunrise,Vishakh and Satheesh were standing in a lawn with their backs towards each other. Vishakh's shadow fell exactly towards his left-hand side. Which direction was Satheesh facing?

$A$ man walked $30 \, m$ towards south. Then,he turned to his right and walked $30 \, m$. Then,he turned to his left and walked $20 \, m$. Again,he turned to his left and walked $30 \, m$. How far is he from his initial position?

From the original position given in the above figure,$A$ and $B$ move one arm length clockwise and then cross over to the corner diagonally opposite. $C$ and $D$ move one arm length anticlockwise and cross over to the corner diagonally opposite. The original configuration $ADBC$ has now changed to:

Johnson left for his office in his car. He drove $15 \, km$ towards north and then $10 \, km$ towards west. He then turned to the south and covered $5 \, km$. Further,he turned to the east and moved $8 \, km$. Finally,he turned right and drove $10 \, km$. How far and in which direction is he from his starting point?

$A$ postman was returning to the post office which was in front of him to the north. When the post office was $100 \, m$ away from him,he turned to the left and moved $50 \, m$ to deliver the last letter at Shantivilla. He then moved in the same direction for $40 \, m$,turned to his right and moved $100 \, m$. How many metres was he away from the post office? (in $m$)

$X$ and $Y$ start moving towards each other from two places $200 \, m$ apart. After walking $60 \, m$,$Y$ turns left and walks $20 \, m$,then turns right and walks $40 \, m$. He then turns right again and comes back to the road on which he had started walking. If $X$ and $Y$ walk with the same speed,what is the distance between them now? (in $m$)
