The average of nadine's six test is 77. The scores on the five of the test are 88,65,75,83 and 90. what is the score on the remaining test? A. 91
B. 81
C. 71
D. 61

The score on the remaining test is x = 61

Hence, option D is correct.      

Step-by-step explanation:

Let 'x' be the score of the remaining test

The average score of Nadine's six tests = 77

so

Average score = (88+65+75+83+90+x) / 6

substituting average score = 77 in the equation to find 'x'

                  77   = (401 + x) / 6

              401 + x = 77 × 6

                        x = 462 - 401

                        x = 61

Therefore, the score on the remaining test is x = 61

Hence, option D is correct.
