If 0 < q < 1, what is the median of the values q, q^-1, q^2, q^1/2 and q^3? Options:
A) q B) q^-1 C) q^2 D) q^1/2 E) q^3
A. To make the problem less confusing, I picked a number between 0 and 1 such as q = 1/4 and calculate:   q = 1/4   q^-1 = 4   q^2 = 1/16   q^(1/2) = 1/2   q^3 = 1/8.   From this, rearrange the number and the median is 1/4, which is q. qnswer q
