Answers
Given : During 'visit Nepal 2020',among 7500 Chinese tourists who visited Nepal,
60% of them had already visited Bhutan,
50% had Sri Lanka, and
30% have visited both the countries.
To Find : information in a Venn diagram.
ii) how many tourists have not visited any of these two countries ( Sri Lanka and Bhutan )
Solution:
Total = 7500
already visited Bhutan, B = (60/100)7500 = 4500
already visited Sri Lanka, S = (50/100)7500 = 3750
already visited both the countries. S ∩ B = (30/100)7500 = 2250
have not visited any of these two countries ( Sri Lanka and Bhutan ) = None
Total = B + S - S ∩ B + None
=> 7500 = 4500 + 3750 - 2250 + None
=> None = 1500
1500 tourists have not visited any of these two countries ( Sri Lanka and Bhutan )
