Can any help me lock down the concept of Vbase through a transformer ? I have attach a problem from Kaplan PE Power exam. I'm stuck on how they  solve for the base voltage on the motor side of the problem.

The have the  solution saying Vbase = 22 (220/25) (13/sqrt3*130) give you 11.1775 as the Vbase , Can some show how to go about this .
