In 2010, in the city of Cirebon flood that hit some of the town, one of his is a town in Tangkil affected by the flooding the worst. Not a few residents in the affected Tangkil diarrhea diseases and skin diseases caused by floods. After the data turned out there were 240 people are exposed to diarrhea disease, 180 people were exposed to diseases of the skin and 150 people were exposed to diarrhea diseases and skin diseases. From this data, specify:

1. population in Tangkil affected diarrhea diseases and skin diseases
2. population which is only exposed to diarrhea disease
3. population which only exposed skin disease
4. If in Tangkil has 550 inhabitants, what is the population which does not fall diarrhea diseases and skin diseases?

Answer:

suppose the affected diarrhea disease: D

the affected skin diseases: K

which is only exposed to diarrhea disease: a

disease that only affected skin: b

affected diarrhea diseases and skin diseases: c

Which does not fall diarrhea diseases and skin diseases: e

• D∪K=a+b-c=240+180-150=270

So, the number of inhabitants in the affected Tangkil diarrhea diseases and skin diseases there are 270 people.

• a=D-c=240-150=90

So, the number of people exposed to diarrhea diseases is only 90 people.

• b=K-c=180-150=30

So, the only population exposed to skin diseases there are 30 people.

• S-D∪K=550-270=280

So, the population does not fall diarrhea diseases and skin diseases there are 280 people.
