20% of the people in a village own a dog, 30% own goats and 40% own cattle, 5% own both a dog and goats, 4% own both a dog and c
attle and 3% own both goats and cattle. If 1% own all three, what percentage of the village own none of the three?
1 answer:
Answer:
37 %
Step-by-step explanation:
here..
only Dog = 20- 5 - 4 - 1 = 10
only goats = 30 - 5 - 3 - 1 = 21
only cattle = 40 - 4 - 3 - 1 = 32
then ... since the maximum percentage is 100 %
people who don't own any animal = 100% - 10% - 21% - 32% = 37 %
