Since there are seven people and median is 4, the fourth highest has to catch 4 fishes
Now three persons would have caught lesser and the other 3 would have caught more than 4 fishes
Since 3 is the mode , lets assume all 3 people who have caught less than 4, have caught 3 fishes each
Now the mean is 5 i.e. there were 35 fishes caught in all.
So they might have caught in this order
3,3,3,4,6,8,8 or 3,3,3,4,7,7,8 or 3,3,3,4,6,7,9 .... many such combinations
