He has $36,000 worth of fish, he sells half at a 20% profit,

He has $36,000 worth of fish, he sells a sixth at a 10% loss,

So now we see how much profit he has so far

So now we see how much profit he wants

So now we see how much more profit he needs to match his goal

Now we find out how much his remaining fish are worth

Now we divide the amount more he wants by the amount he has left

so he must sell the remaining fish at 20% profit
