Zp = n^2 * Zs.
Here Zp is parallel combination of two 16 ohm R,
So their resultant is 8. Now put vales in equation you will get n = 0.6003.
So for matching 22.2*0.60 = 8 ohm.

Zp = n^2 * Zs.
Zp = Parallel combination of two 16 Ohm resistors.
Given,
Zs = Series Impedence/ Resistance = 22.2 Ohm.
n = no.of turns = 0.60.
Zp = Parallel combination of two 16 Ohm resistors.
Given,
Zs = Series Impedence/ Resistance = 22.2 Ohm.
n = no.of turns = 0.60.

Zp = n^2 * Zs.
8 = 0.60 * 0.60 * 22.2.
8 = 7.992.
8 = 0.60 * 0.60 * 22.2.
8 = 7.992.

Formula of relation between the primary and secondary:
((Np)^2)(Zp)=((Ns)^2)(Zs).
Since the primary (Zp) has two 16-ohm parallel it would result to 8-ohms in total (Zp = 8ohms).
Substituting through trial and error given by choices:
((1)^2)(8)=((0.6)^2)(22.2).
8 = 0.60 * 0.60 * 22.2.
8 = 7.992.
((Np)^2)(Zp)=((Ns)^2)(Zs).
Since the primary (Zp) has two 16-ohm parallel it would result to 8-ohms in total (Zp = 8ohms).
Substituting through trial and error given by choices:
((1)^2)(8)=((0.6)^2)(22.2).
8 = 0.60 * 0.60 * 22.2.
8 = 7.992.
