Answer:
80 students
Step-by-step explanation:
The line in the middle of the box is the 50% line ( the median, which is 50% above and 50% below)
Since it is at 48, there are 50% above 48 points
3/4 of the students had less than 70 marks
3/4 s = 120
s = 4/3 * 120
The number of students = 160
We need 50 % of the students
50% of 160
.5 * 160 = 80
