Hi All,

When given variables in Data Sufficiency Quant questions, is one allowed to assume that all the variables represent different values?

For example: Is s equal to the median of the four positive integers r, s, t, and u?

Without being told that r is smaller than [s, t, u] and that [s, t,u] are consecutive integers, is the assumption that the variables represent unique numbers because the variables are different letters OK on the exam?

NO, you cannot assume two different variables to represent different numbers unless given in the question.

a and b does not mean different integers or fractions. you have to take a=b and text the question.

Variables can be anything unless specified so you have to text them for everything. Positive, negative, integers, fractions, 0 etc
