Let the turns ration be k.
k =N2/N1.
Now, we know that V1/V2 = N1/N2.
24/V2 = 1/20 [as k = N2/N1],
V2= 240v.
k =N2/N1.
Now, we know that V1/V2 = N1/N2.
24/V2 = 1/20 [as k = N2/N1],
V2= 240v.

20 Ratio Mean Primary is 1turn and secondary turns are 20
So if secondry voltage is 12 V
So 20*12=240volts
So if secondry voltage is 12 V
So 20*12=240volts

Solution:
Turns ratio(K) = 20.
Primary voltage = 12.
N2/N1 = V2/V1.
V2 = N2/N1*V1.
V2 = 20*12 = 240V.
Turns ratio(K) = 20.
Primary voltage = 12.
N2/N1 = V2/V1.
V2 = N2/N1*V1.
V2 = 20*12 = 240V.

Turn ratio = N1/N1=20.
Transformation ratio = V2/V1 = N2/N1.
i.e, V2/V1= 1/20.
V2 = 12/20,
V2 = 0.6 .
Transformation ratio = V2/V1 = N2/N1.
i.e, V2/V1= 1/20.
V2 = 12/20,
V2 = 0.6 .

Turning ratio = n2/n1 = 20 .
Primary volt = 12v.
Sec. volt = ?
n2/n1 = v2/v1.
20 = v2/12.
v2 = 240v.
Primary volt = 12v.
Sec. volt = ?
n2/n1 = v2/v1.
20 = v2/12.
v2 = 240v.

We know,
N2/N1=E2/E1=K
According to question
N2/N1=E2/12=20
=>20=E2/12
=>E2=12*20
=240V
N2/N1=E2/E1=K
According to question
N2/N1=E2/12=20
=>20=E2/12
=>E2=12*20
=240V

K=N2/N1= V2/V1 no of turns ratio is 20, primary voltage 12 due to which V2 = 20x12 = 240 Volt.

v2/v1 = n2/n1 = i1/i2 = k (this is standard ratio)
n2/n1 = 20 (given)
20=v2/v1
v2=20*12
=240
n2/n1 = 20 (given)
20=v2/v1
v2=20*12
=240

k = v2/v1; v1 = primary voltage = 12.
Turns ratio k = 20.
So 20 = v2/12 i.e., v2 = 240v.
Turns ratio k = 20.
So 20 = v2/12 i.e., v2 = 240v.

Turns ratio= 1/k.
So 1/k = v1/v2.
20 =12/v2,
v2 = 12/20,
v2 =0.6v.
So, Options are wrong.
So 1/k = v1/v2.
20 =12/v2,
v2 = 12/20,
v2 =0.6v.
So, Options are wrong.
