Hi Bunnuel,

I solved this as follows...
Class Frequency Class mark
Class 0-9.5 Frequency 1 Class mark 4.75
Class 9.5-19.5 Frequency 4 Class mark 14.5
Class 19.5-29.5 Frequency 6 Classmark 24.5
Class 29.5- 39.5 Frequency 7 Classmark 34.5
39.5-49.5 Frequency 2 Class mark 44.5

Median is 24.5......consider pages from 18.5 to 30 ( +6, -6).....
Q1 Least....Assuming 7 students wrote 39.5pages, 4 wrote 18.5 pages, 6 wrote 19.5 pages.Least 6-4=2.
Q2 Maximum 7+6+4 = 17.

Please let me know if it is correct.
