Question 1205890
.


Generally speaking, in mathematical problem books it is not customary 
to ask students to solve problems based on a context.
Because who knows what is inside of the author’s head . . .


Yes, sometime students are forced do it, when the author is not able 
to present the context explicitly using his own words - - - or is not able
to do it properly; or do not want to make necessary efforts . . . 


But this is usually considered as a bad accident and DEFINITELY is NOT a good practice.


In any case, it does not speak well about the authors of such problems, when they 
ask students solve a problem based on a context.


When a reader sees such invitation from the author to solve a Math problem based on a context,
a reader (and all people around) may think whether the author needs health procedures to improve his brain . . .
