Q.

Consider a seating plan of students in an auditorium. Push all the seats together and represent each seat with a square. Each square describe the position of each student with two independent information

a) The row in which he/she sits.

b) The column in which he/she sits.

Now, if the student 'A' is sitting in the third row and the fifth column. find the position of his friend sitting two columns away(to A's right-hand side).

1. It cannot be determined

2. It can be determined on a single number line

3. I do not know

4. It requires two number lines
