1) Turns ratio in terms of number of turns is given by = higher number of turns/lower number of turns.
2) Turns ratio in terms of voltage is given by= low voltage/high voltage.
2) Turns ratio in terms of voltage is given by= low voltage/high voltage.

Turn ratio is always N1/N2 which is always inverse of transformation ratio K & K=N2/N1.
Here the answer is 0.2.
Here the answer is 0.2.

The answer is wrong there is a difference between the turn ratio and transformation ratio.
So, the Answer should be 400/2000= 0.2.
So, the Answer should be 400/2000= 0.2.

Turns ratio.
I think n1/n2 because transformation ratio is n2/n1 once you cross I agree @Jyothi.

Turn Ratio:
It is defined as the ratio of primary to secondary turns.
TR= N1/N2.
and
Transformation Ratio
The transformation ratio is defined as the ratio of the secondary voltage(or turns) to the primary voltage(or turns). It is denoted by K.
K= (E2/E1) or (N2/N1) or (I1/I2).
It is defined as the ratio of primary to secondary turns.
TR= N1/N2.

Answer is 0.2.
Turns ratio is n1/n2.
Transformation ratio is n2/n1.
Turns ratio is n1/n2.
Transformation ratio is n2/n1.

The turns ratio=n1/n2.
400/2000=0.2.
400/2000=0.2.
