Question 20. The picture shows the page for one month of a calendar without any of the dates.  The total of the dates for the two shaded days is 29. On what day of the week does the first day of the month fall?  Let's begin this problem with labeling the first shaded date with an X. Then we can simply start adding days to X until we get to the second shaded square, which will be X plus 13.  We know that the two shaded squares have a sum of 29, which is represented by X plus X plus 13  is equal to 29. We subtract 13 from both sides getting X plus X equal to 16. Now all we have to do is divide that by 2 and get X equals 8.  And with this information, we know that the first shaded square is the 8th of the month.  Simply, we need to work backwards and we get that Thursday is the first day of the month. So the answer will be D.
