What is the numerical representation of THOUSAND/TOU SAND?

The numerical representation of "THOUSAND" is 1000. This term is widely recognized across various contexts to signify a quantity that is equal to one thousand units. In both everyday usage and mathematical contexts, it serves as a standard reference point.

The other options, while they represent different numeric values, do not accurately encapsulate the meaning of "THOUSAND." For instance, 100 is a representation of one hundred, 500 signifies five hundred, and 2000 represents two thousand; each of these values is distinct and does not align with the definition of "THOUSAND." Thus, 1000 remains the correct answer as it directly corresponds to the established numerical term.
