Answer:

Hey mate,

(a) We can arrange the series in ascending or descending order.

Ascending: 39,48,56,75,76,81,85,85,90,95.

Highest marks are 95 and lowest marks are 39.

(b) Mean means average. So,average of this series:

(39+48+46+75+76+81+85+85+90+95)/10

=730/10

=73

(c)No. of students securing marks more than mean marks i.e. 73 are:

75,76,81,85,85,90,95

Counting these we get the answer as 7.

Hope it helps

If so, then please mark the brainliest.
