Cpa intangible assets, where did 975 come from?

From equation 975= book value of intangible assets * 175%- book value of intangible assets = (900+400) *175%-(900+400)

Among them, the book value of intangible assets * 175% is tax basis, and the asset tax basis is greater than the book value, resulting in differences. However, the difference formed in this question will not be reversed in the future, so it can be understood as a permanent difference, so it is not included in the deferred income tax liability.

Please adopt it if it is useful.
