Who had caught the most, second most, third most and least?

Question

Asif, Dhanush, Hari and Rohan were counting up the results of a day's fishing:
Rohan had caught more than Hari.
Between them, Asif and Dhanush had caught just as many as Hari and Rohan.
Asif and Rohan had not caught as many as Dhanush and Hari.
Who had caught the most, second most, third most and least?

Answer 1

R>H
A+D=H+R ----> (1)
A+R=D+H ----> (2)
From (2) we have D>A as R>H
If R=H+n and D=A+m
(1) ---> A+D=2A+m, H+R=2H+n
(2) ---> A+R=A+H+n, D+H=A+m+H --> m=n ---> A=H ---> D=R
Rohan & Dhanush are equal, the most and second and Asif & Hari are equal and share 3rd and 4th place
