Given S=2t
In any options , if the denominator is equal to 0, that options cannot be determined.
In I, 2t/s , S cannot be 0 m if s/t =2. So this can be determined.
In II, s-t/t , t cannot be 0 if s/t =2. So this can also be determined
Now, In III , s-1/t-1 , denominator t-1 can be 0 if s/t=2 (s=2, t=1) So this cannot be determined.
Hence Answer is C, I and II can be determined.

Since s = 2t, we can substitute 2t for s in each expression:BTGmoderatorDC wrote:If s/t = 2, then the value of which of the following can be determined?
