A simple procedure within the $1/N_c$ expansion method where all the $N_c$quarks are treated on the same footing has been found successful in describingmixed symmetric negative parity baryon states belonging to the $[{\bf70},\ell^-]$ multiplets %with $\ell$ = 1, 2 or 3. of the $N$ = 1 and 3 bands.Presently it is applied to mixed symmetric positive parity $[{\bf 70},0^+]$ and$[{\bf 70},2^+]$ multiplets of the $N$ = 2 band. We search for the mostdominant terms in the mass formula. The results are compared to those obtainedin the procedure where the system is separated into a core and an excitedquark. We find that both the spin and isospin operators of the entire system of$N_c$ quarks play dominant roles in describing the data, like for negativeparity states. As a by-product we present the contribution of the leadingspin-isospin singlet term as a function of the band number, which hints atdistinct Regge trajectories for the symmetric and mixed symmetric states.
