A plethora of investigations have been carried out in studying inequalities for the Fourier coefficients of weakly holomorphic modular forms, for example, the partition function. Recently, Bringmann, Kane, Rolen, and Tripp studied asymptotics for the k-colored partition function and more generally, for the fractional partitions arising from the Nekrasov-Okounkov formula which in turn allowed them to prove generalized multiplicative inequalities. Motivated by their idea to find interesting inequalities for the k-colored partition functions, denoted by pk(n)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$p_k(n)$$\end{document}, in this paper, we prove a family of inequalities for the p24(n)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$p_{24}(n)$$\end{document}.
