Answer 1

I think you are asking about the productivity comparison of two years 
productivity will be more if rate of output is higher 
For first year rate of output is 12/4=3 fish per hour 
For second year rate of output is 15/6=2.5 fish per hour  
So we can see that Jim was more productive in first year as compared to second year
