For Maria, 20th from the front of the line means #20 in the line.
For her classmate, 23rd from the end of a line of 35 means there are 35-23 = 12 in front of her, which means she is #13 in the line.
If the question is really how many classmates Maria has, the answer is 20-13 = 7.
If the question is supposed to be how many students are in Maria's class, then the answer is (20-13)+1 = 8.
