Question: The man who works in Wipro has a e-mail account with?
Explanation:
Construct a table with the names of the graduates, companies, locations and email providers.
Note that the company and location are given as a pair.
Thus, if one of these two parameters is known for a person or corresponding to an email provider, the other is also automatically known.
From (ii), we get: HCL – Noida – Sancharnet and Tisco – Jamshedpur – Indiatimes.
Now, consider the information which directly mentions the location, company or provider for a person.
Rahul works for Telco in Pune and uses Rediffmail.
Kabeer works for Usha Martin in Kolkata and Anup works for Tisco in Jamshedpur.
Thus, the table is as shown below:
Now, since neither Alok nor Raghu work in Noida, Amit works for HCL in Noida.
Therefore, Amit uses Sancharnet.
Similarly, Anup uses Indiatimes.
Thus, the table becomes:
Since Alok does not work for Mecon, Raghu works for Mecon and Alok works for Wipro.
Therefore, Alok and Raghu work in Bangalore and Ranchi respectively.
Since the person who works in Mecon has an account with Gmail, Raghu has an account with Gmail.
Since the person who works in Wipro does not have a Yahoo account, Alok has to have a Hotmail account and Kabeer has to have a Yahoo account.
Thus, the final table is as shown below:
Thus, the person who works in Wipro has an e-mail account with Hotmail.
Hence, option (d).
