\(\frac{n_1 + n_2 + n_3 + n_4 + n_5}{{5}} = 88\)

\(n_1 + n_2 + n_3 + n_4 + n_5 = 440\)

\(\frac{n_1 + n_2 + n_3 + n_4 + n_5 + n_6}{{6}} = 90\)

\(\frac{440 + n_6}{{6}} = 90\)

\(440 + n_6 = 540\)

\(n_6 = 100\)

Pick D.

sum of 5 scores= 88*5 ; 440
sum of 5 scores + 6th score = 540-440 ; 100

An innovative way to answer such questions

The average scores of 5 quizzes 88 is short of 2 points from desired average score

i.e. Total shortfall of 5 quizzes = 2*5 = 10 points

i.e. the next quiz must compensate the shortfall over it's average maintaining score 90

i.e. score in next quiz required = 90+10 = 100

Answer: Option D
