Prof. Singh has been tracking the number of visitors to his homepage. His service provider has provided him with the following data on the country of origin of the visitors and the university they belong to:
âââââââ
âââââââ
University 1 can belong to ______.
Answer & solution
- A
UK
- B
Canada
Netherlands
- D
USA
Let us denote University 1 as U1, University 2 as U2 and so on.
Consider day 3. 2 students from UK and 1 student from USA visited the homepage. Also, 2 and 1 student from U4 and U6 respectively visited the homepage.
∴ U4 is in UK and U6 is in USA. Similarly, considering day 2, U3 is in Netherlands and U8 is in India.
Canada has 2, 0 and 0 visitors on days 1, 2 and 3 and so have U2 and U7. ∴ One of U2 and U7 is in Canada.
UK has 2, 0 and 2 visitors on days 1, 2 and 3 and we know that U4 is in UK. But as U4 has 0 visitors on day 1, we can say that either U2 or U7 is in UK. (If we assume that UK has three of the eight listed universities, U4, U1 and U5, then considering the number of visitors on day 1, we do not find appropriate universities for India and Netherlands.)
Similarly, considering India and Netherlands, U5 and U1 will be in these countries. Thus, we have the following table.
âââââââ
∴ University 1 can belong to Netherlands or India.
Hence, option (c).
