Hi all,
In an examination, each student in a group scores either 8, 12, 16 or 20 marks. The number of students scoring each mark is shown in the table below. If the median mark is 12, then the largest the possible value of x will be:
Mark 8 12 16 20
Number of students 10 20 x 10
A) 49
B) 59
C) 69
D) None of these
Just guide how to solve it and then I will solve it by myself. Any help will be highly appreciated.
Thanks and Regards
