~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



        I am strongly disagree with the solution given by @CPhill in his post.



First,  his interpretation is far-fetched.   Nothing in the problem points 
to triangle and its midline and so on.


But even if to accept his interpretation,  his answer  1/4  for the area ratios
is   {{{highlight(highlight(fatally))}}}  {{{highlight(highlight(incorrect))}}}.


Yes,  the ratio  1/4  is valid as the ratio of the area of smaller triangle to the area of the whole triangle.



But the question is about the ratio of the areas of differently colored parts.



The ratio of the area of smaller triangle to the area of the remaining part 
of the whole triangle is then  1/3,


and the correct  {{{highlight(highlight(ANSWER))}}}   should be  then  {{{highlight(highlight(1/3))}}}.
