Why shouldn't be N1/N2 = v1/v2
thus, N1/N2 = 120/900 = .133
isn't that right ??

Answer will be 0.13.
Because turn ratio is inverse of transformation ratio.

I agree with Mahijagadeesh
this answer is incorrect
It should be 0.13v
this answer is incorrect
It should be 0.13v

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

Please help me that where we can use n1/n2 and where we can use n2/n1?

It is step up transformer so,
N2/N1=V2/V1,
N2/N1=900/120,
N2/N1=7.5.
N2/N1=V2/V1,
N2/N1=900/120,
N2/N1=7.5.

To step up by means N2/N1 high voltage to low and step down N1/N2.

I agree with 0.13 the 7.5 is k.
Turns ratio = 1/K,
1/7.5 = 0.13.
Turns ratio = 1/K,
1/7.5 = 0.13.

Is turns ratio different for step up and step down transformer?

Turns ratio is primary to secondary. So the answer is wrong.
