Did somebody explained you some-when that every post to this forum must have a question ?

Or you need a special explanation ?


It seems  SO  STRANGE  TO  ME,  because it is  TOTALLY  OBVIOUS.


By the way,  simple courtesy just assumes/requires that an educated person  MUST  ASK  A  QUESTION,  when he comes for help.


Isn't it is so ?


Are you an educated person ?


Did your parents,  or other relatives,  or in the school teach you about it ?


The routine rule of the life is: 

    When you communicate with people in a polite, courtesy way, you make friends.

    Otherwise, you create enemies.

PERSON           AGE
Mrs. Chen          c
Mark               c+7
Eric               c-11
SUM                149

You can find the age of each person. Setup the needed equation.
