Umesh directly went from P, to Q which is 9 feet distant. Then he turns to the right and walked 4 feet. After this he turned to the right and walked a distance which is equal from P to Q. Finally he turned to the right and walked 3 feet. How far is he now from P?

If he starts walking the morning then finally he will face towards South and if he starts in the evening then finally he will face towards North.

It is clear from the diagrams that new name of West will become South-East.

In the evening sun sets in West. Hence then any shadow falls in the East. Since Hema's shadow was to the right of Hema. Hence Rekha was facing towards South.

In the morning sun rises in the East. Hence then any shadow falls in the West. Since Nikharia's shadow was exactly to the right of Nivedita. Hence Nikharia is facing towards North.

Hence M is in the East of K.

S is to the South-West of R.

Sun rises in the east in the morning. Since the shadow of Suresh falls to his right. So he is facing South.
