Two positions of a dice are shown below. When number '1' is on the top. What number will be at the bottom?

According to the rule (2) when 3 points are at the bottom then 4 points will be at the top.

In these two positions one of the common face having 1 point is in the same position. Therefore according to rule (2). There will be 4 points on the required face.

The adjacent faces to the face which 3 points have 2, 1, 4 and 6 points. Hence on the face which is opposite to the face which contains 3 points, there will be 5 points.

As the numbers 2, 3, 4 and 5 are adjacent to 6. Hence the number on the face opposite to 6 is 1.

According to the rule no. (3), common faces with number 2 are in same positions. Hence when the digit 5 is on the bottom then 1 will on the upper surface.

Here one of the two common faces (5) is in the same position, then according to the rule no (2) the remaining face with the 4 dots will be opposite to face with dots 2.

Hence finally Sujata will face towards North.

Q is in South-East of R.

Sun rises in the east. So the shadow of a man will always falls towards the west. Since the shadow of Stephen is to the right of Vimal. Hence Vimal is facing towards South.
