V1= 60v,
T=3:1 then we have n1=3 and n2=1.
N2/N1=V2/V1 1/3=V2/60.
So we get V2= 20v.
OR N1/N2=V1/V2 also we get 20v.
T=3:1 then we have n1=3 and n2=1.
N2/N1=V2/V1 1/3=V2/60.
So we get V2= 20v.
OR N1/N2=V1/V2 also we get 20v.

Solution:
Primary voltage(V1) = 60V.
Turns ratio(K) = N2/N1 = V2/V1.
V2 = N2/N1*V1.
V2 = 1/3*60 = 60/3 = 20V.
Primary voltage(V1) = 60V.
Turns ratio(K) = N2/N1 = V2/V1.
V2 = N2/N1*V1.
V2 = 1/3*60 = 60/3 = 20V.

Turn ratio = N2:N1 = 3:1.
This is the basic fundamental all we have to aware.
Now solve answer is 180.

If the transformer Ratio is 3 or any other numbere given as single digit then we have to consider n2:n1.

V2 / V 1= N2 / N1,
V2 / 60 = 1/3,
V2 * 3 = 60 * 1 (Cross Multiplication),
V2 = 60 / 3,
V2 = 20 V.
V2 / 60 = 1/3,
V2 * 3 = 60 * 1 (Cross Multiplication),
V2 = 60 / 3,
V2 = 20 V.

Turn ratio was given as 3:1 that means n2=3 and n1= 1 and I agree to @Rohinthh.

k=n2/n1.
n2=1.
n1=3.
Then v2/v1=n2/n1.
v2/60=1/3.
3v2=60.
v2=60/3.
v2=20.
n2=1.
n1=3.
Then v2/v1=n2/n1.
v2/60=1/3.
3v2=60.
v2=60/3.
v2=20.

Transformation ratio is N2/N1 and Turns ratio is N1/N2 is this right?

Answer is 180.
Ns/Np=3/1.
Vs=?
Vp=60.
Ns/Np=Vs/Vp=3/1=Vs/60.
Vs=180v.
Ns/Np=3/1.
Vs=?
Vp=60.
Ns/Np=Vs/Vp=3/1=Vs/60.
Vs=180v.

Turns ratio = transformer ratio = N2/N1=3/1.
So solve and get 180.
So solve and get 180.
