K=N2/N1=E1/E2
Given that; K=20,E1=12V
20=E2/12
E2=240V
Given that; K=20,E1=12V
20=E2/12
E2=240V

Ratio=N2/N1=V2/V1
V2=V1*RATIO
=12*20
=240V
V2=V1*RATIO
=12*20
=240V

In transformer
t1/t2=v2/v1
20=v2/12,
v2=20*12=240
t1/t2=v2/v1
20=v2/12,
v2=20*12=240

Its simple taking voltage turns ratio: V1/V2 = N1/N2.

VS/VP = TS/TP.
VS = VP*20.
VS = 12*20.
VS = 120 V.
VS = VP*20.
VS = 12*20.
VS = 120 V.

Answer is 0.6. The turns ratio is N1/N2 not N2/N1.

v2/v1=n2/n1=k
here k=20,v1=12v
v2/12=20
v2=240v
here k=20,v1=12v
v2/12=20
v2=240v

n1/n2 = v1/v2.
20 = 12/v2.
v2 = 12/20 = 0.6 v.
20 = 12/v2.
v2 = 12/20 = 0.6 v.

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

E1/E2=N1/N2;
N1/N2=20; so E2=20*12=240volts
N1/N2=20; so E2=20*12=240volts
