Why they give turns ratio?

In a transformer the ratio of primary to secondary is 9 : 4 if power input is P, what will be the ratio of power output to the power input?

i/p power 10V then o/p 10v is called ideal transformer.

Is load power factor required in the question?

Basically, the ideal transformer ratio is 1:1. So the primary power is 25watts and also secondary power 25 watts.
1 : 1 = 25 : 25.
1 : 1 = 25 : 25.

Basically ideal transformer means I/P = O/P.
So 25kw = 25kw.
So 25kw = 25kw.

In an ideal transformer vpip = voio means input voltage x input current =output voltage x output current. But if the secondary is shorted the output voltage become zero, however output current is not zero.
Then the formula above fails. exp vp=230V, ip=5A and vo=0v the primary vpip=230 x 5 and secondary voio=0x io=0VA so vpip is not equal to voio. Then the above formula fails, is it not ?
