$\huge \boxed { \blue{\bold{Answer}}}$

Arrange in ascending order:-

39, 48, 56, 75, 76, 81, 85, 85, 90, 95

Highest mark = 95

Lowest mark = 39

______________________________

Range = Highest - Lowest

95 - 39

= 56

______________________________

Mean = Total marks/ number of students

$\frac{39 + 48 + 56 + 75 + 76 + 81 + 85 + 85 + 90 + 95}{10 } \\ \\ \frac{730}{10} \\ \\ = 73$
