Out of the 100% selling price, the margin is 60%. Now, you need to pay fro the expenses with your margin.
Staffing = 35%
Remaining money = 60% - 35%
Remaining money = 25%
Now, 10% goes to rent
Remaining money after paying rent = 25% - 10% = 15 %
Now, 5% goes to miscellaneous expenses
Hence, the remaining money after paying all the expenses = 15% - 5%
Profit = 10%
Hence, you are making a profit of 10%.
