Tsunami in Japan was happened on march 2011, there was many victims, minimal 1600 human corpses flutter and did not take care. So, it needed some SAR team to bury them. Twenty members of SAR team could bury all of human corpses in ten days, but they could finish in five days in order to the human corpses were not decay. How many person of SAR team  must be added in to bury them can be finished in five day.

We can solve this problem with flip over comparison:
Assume all of SAR team that needed is X.
20/5 = X/10
200 = 5 X
5X = 200
X = 40
The member who must be added is : 
40-20=20

So, 20 people who must be added to bury the victims can be finished in five day.
