Question 1146084
Tutor ikleyn and others
A big part of solving problems in the real world is to know what is needed and what is not needed to solve a problem.
Your dislike of such "trick" questions is pure academic snobbery.
If you don't like such problems then avoid them.
Stick to solving problems that suit you.
BTW I don't admit that it is "pure US american" style. The style of having extraneous info is valid for teaching real world problems.
