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.

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

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

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.

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

In ideal transformers efficiency is 100%.

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

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.

Transformer ratio does not have any effect of transformer power.
Transformer power is same in both side & only voltage and current are variable.

Because this Transformer is IDEAL transformer. Then no loss in the ideal transformer.
