UGC NET Questions (Paper – 1)

In non-positional systems such as Roman numerals, symbols have fixed values that do not change with position. The total value is obtained by combining these fixed-value symbols using certain rules rather than place weights. Such systems are therefore termed non-positional.

Option A:
Option A accurately describes systems where there is no concept of positional weights tied to powers of a base. The symbol's meaning is fixed and does not depend on place value.

Option B:
Option B, positional, describes systems like decimal and binary where the position of a digit is critical in determining its contribution. This is the opposite of what the question describes.

Option C:
Option C, weighted, is associated with positional systems in which each position carries a specific weight, again contradicting the description.

Option D:
Option D, mixed-radix, refers to systems where different positions may have different bases, as in time representation (hours, minutes, seconds), and is not solely about position independence.
