Answer 1

Answer:

Assume that in the first group there are x - students, second group y - students and third group z - students, we have to find x+y+z.

each student wrote a report with 9 pictures in it, that means x+y+z people had 9(x+y+z)- pictures in the report that equals 585, so x+y+z = 585/9=65,

The answer is 65.

and if each report were prepared by 3 students then answer is actually 65*3=195 students, it depends.
