Question

5 quizzes were held. John got an avg of 32 marks . The diff between his lowest score and highest score was 10. What is the max score he can get for the highest quiz?

Answer 1

Step-by-step explanation:

let the highest score be x

as per the question,

lowest score = x - 10

sum of all the 5 quizzes = 5x32 = 160

now,

$= > x - 10 + x < 160 \\ \\ = > 2x - 10 < 160 \\ \\ = > x - 5 < 80 \\ \\ = > x < 85$
