In this paper, the problem under consideration is multiobjective non-linear fractional programming problem involving semilocally convex and related functions. We have discussed the interrelation between the solution sets involving properly efficient solutions of multiobjective fractional programming and corresponding scalar fractional programming problem. Necessary and sufficient optimality conditions are obtained for efficient and properly efficient solutions. Some duality results are established for multiobjective Schaible type dual. Keywords: Nonlinear Programming, Multi-Objective Fractional Programming, Semilocally Convex Functions, Pseudoconvex Functions.
