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.

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

In ideal transformer, efficiency always 100%.
Input power == output power.
So ans is 25.
Input power == output power.
So ans is 25.

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

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

If the transformer is ideal then,
Input power = Output power.
Answer is 25W.
Input power = Output power.
Answer is 25W.

Because transformer is ideal so power is equal in both primary and secondary.
