The answer is n1/n2 i.e 0.2.

Actually, the turns ratio means n1/n2 so 400/2000=0.2.
The ans 5 i.e 2000/400 for transformation ratio=n2/n1.
The ans 5 i.e 2000/400 for transformation ratio=n2/n1.

The answer is wrong. "Transformation ratio" and "turns ratio" are one and the same thing, the formula is N1/N2 = V1/V2 = I2/I1.
The answer is k = 400/2000 = 0.2.
The answer is k = 400/2000 = 0.2.

I agree @Rajkumar.
Second thing is that they can never be fractional it is always integral.

This is wrong because turns ratio different from transformation ratio.
Transformation ratio = k = n2/n1.
Turns ratio =1/k=n1/n2.
Transformation ratio = k = n2/n1.
Turns ratio =1/k=n1/n2.

It's wrong turn ratio =n1/n2.
So, answer = 0.2.
So, answer = 0.2.

N1/N2 =400/2000 = 0.2.
Correct answer
N2/N1 = transformation ratio.
Correct answer
N2/N1 = transformation ratio.

Turns Ratio = Np/Ns.
It depends upon how the winding is connected.
In the given question,
Np = 400.
Ns = 2000.
Hence, Np/Ns= 400/2000 = 0.2.
So the turn Ratio is 0.2.

Turns ratio is N1/N2.
Transformation ratio is N2/N1.
So, the answer is 0.2.
Transformation ratio is N2/N1.
So, the answer is 0.2.

Turns ratio and transformation ratio both are different. So this answer is wrong.
