LetF(a, b; c; x) be the Gaussian hypergeometric series and for 0 < r < 1 let[formula]G. D. Anderson, M. K. Vamanamurthy, and M. Vuorinen raised recently the following problem: For whicha, b ∈ (0, 1) does[formula]hold for allr, s ∈ (0, 1)? They also proved this inequality fora = b = 1/2. The main purpose of this paper is to give an answer to this problem fora + b = 1 and to find a lower bound for the summ(r) + m(s) fora ∈ (0, 2) andb ∈ (0, 2 − a].
