Consider the strong electrolytes Z$$_m$$X$$_n$$, U$$_m$$Y$$_p$$ and V$$_m$$X$$_n$$. Limiting molar conductivity ($$\Lambda^0$$) of U$$_m$$Y$$_p$$ and V$$_m$$X$$_n$$ are 250 and 440 S cm$$^2$$ mol$$^{-1}$$, respectively. The value of (m + n + p) is _______.

Given:

Ion	Z$$^{n+}$$	U$$^{p+}$$	V$$^{n+}$$	X$$^{m-}$$	Y$$^{m-}$$
$$\lambda^0$$ (S cm$$^2$$ mol$$^{-1}$$)	50.0	25.0	100.0	80.0	100.0

$$\lambda^0$$ is the limiting molar conductivity of ions

The plot of molar conductivity ($$\Lambda$$) of Z$$_m$$X$$_n$$ vs c$$^{1/2}$$ is given below.
