You are correct @Veena. I agree with you.

K(Turning ratio)=V2/V1
V2=20*12
=240v
V2=20*12
=240v

K=N2/N1=V2/V1
20=V2/12
V2=12*20
V2=240V
20=V2/12
V2=12*20
V2=240V

V2/V1=N2/N1.
V2/12=20.
V2=20*12=240.
V2/12=20.
V2=20*12=240.

v1/v2 =1/k.
12/v2 = 1/20.
v2 = 240v.
12/v2 = 1/20.
v2 = 240v.

vs/vp=20
vs/12=20
vs=20*12
vs=240
vs/12=20
vs=20*12
vs=240

n1/n2= 1/20=vi/v2
20*12=240
20*12=240

Very simple::.
20*12=240.
20*12=240.
