In naphthalene number of `sigma bonds = x` and number of `pi bonds = y`then the value of `(x-y)`

The number of pi bonds in naphthalene is y, number of sigma bonds in z and number of carbon atoms is x. calculate the value of (y+z)/(x) ?

In phosphorus acid, If X is number of non-bonding electron pairs. Y is number of sigma -bonds and Z is number of pi -bonds. Then calculate value of "YxZ-X" .
