ANSWER :
First we will see that a person is working 78 hours in a week and he worked for 49 weeks.
so, First we define product = 78 X 49 = 3122
Now we need to find the hourly wage of the person.
So in order to find the hourly wage of the person we need two things.
1. How much hours he had worked (=3122).
2. Total amount paid to that person(=711190).
Therefore, hourly wage = 711190/3122 = 227.799488
Since we need the answer in two decimal places, The answer is 227.80.
