Some strong and electromagnetic decay processes of mesons are studied in the context of Mitra's version of the relativistic quark model involving broken SU(6) times O(3) group structure in conjunction with Schwinger's technique of partial symmetry and the hypothesis of vector-meson dominance. In particular, we calculate the decay rates and the corresponding branching ratios for the processes (A$sub 1$, A$sub 2$) $Yields$ $gamma$$pi$, $omega$$pi$$pi$; B $Yields$ $gamma$$pi$, rho$pi$$pi$; $omega$ $Yields$ 3$pi$; eta $Yields$ $pi$$sup 0$$gamma$$gamma$, $pi$$pi$$gamma$; and $pi$$sup 0$ $Yields$ 4$gamma$. Comparison of the predicted results with experiment is discussed.
