The results presented in [γ, 11] are extended in our article. Coupled lower and upper solutions, Arzela-Ascoli theorem and Schauder's fixed point theorem play an important role in establishing the arguments. Some examples are taken to ensure the validity of the theoretical results.eninfo:eu-repo/semantics/openAccessArzela-Ascoli TheoremCoupled Nonlinear Boundary ConditionsLower And Upper SolutionsNonlinear Coupled SystemSchauder'S Fixed Point TheoremCoupled Lower and Upper Solution Approach for the Existence of Solutions of Nonlinear Coupled System With Nonlinear Coupled Boundary ConditionsArticle351N/AQ399117
