Soln: In the ideal transformer primary is equal to secondary.
Because it has a 1:1 ratio.
So, Input power = Output power.
25watts = 25watts.
Because it has a 1:1 ratio.
So, Input power = Output power.
25watts = 25watts.

Since it is an ideal transformer, power at primary winding is same as secondary winding.

In ideal transformers efficiency is 100%.

If it is not ideal transformer then what will be the answer ? and please tell the methods.

No losses is observe. That is why it is called ideal.
So 25 watts will remain in the output.
So 25 watts will remain in the output.

Transformer is a constant power, constant frequency, constant flux device irrespective of load.

Yes it is right in ideal transformer input power is equal to output power and it is constant.

It is true that transformer is a static device. And it transform voltage from one level to another level, by keeping frequency and power constant. Ideal condition losses are 0 and input power=out power. In practical case losses are consider so answer is 25W.

In transformer constant power so their is no change in input and output power.
i.e. Answer is 25w.
i.e. Answer is 25w.

Basically for an ideal transformer in ieal condition losses are zero & its efficiency is 100%, also whatever primary side input that will be secondary output...
so the answer will be 25W....
so the answer will be 25W....
