Answer:

80 students

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
