Finally, what is the correct answer?

Yes, @Ahmed.
The answer should be 0.13.
Here the problem is asking turns ratio, not transformation ratio.

Is it same for V2/V1, R2/R1 & I1/I2?

N2/N1 = V2/V1.
900/120 = K=7.5.
900/120 = K=7.5.

Turns ratio means ratio of high voltage side to low voltage side turns.

Turns ratio k = v2/v1.
Here, k = Turns ratio of transformer.
v2 = Secondary voltage of transformer.
v1 = Primary voltage of transformer.
Here, k = Turns ratio of transformer.
v2 = Secondary voltage of transformer.
v1 = Primary voltage of transformer.

The ratio of a four-to-one step-down transformer is written as 4:1.The ratio of a one-to-four step-up transformer should be written as 1:4. Notice in the two ratios that the value of the primary winding is always stated first.

Is turns ratio different for step up and step down transformer?
N2/N1 is transformation ratio while,
N1/N2 is turns ratio, Is not it right. I am very much confused. Please help me?

Turns ratio=N1/N2. (step down).
Turns ratio=N2/N1. (step up).
If not mentioned the type of tx by default consider step up.
Turns ratio=N2/N1. (step up).
If not mentioned the type of tx by default consider step up.
