Please read the below given text for solving the question Each question given below has a problem and two statements numbered I and II giving certain information. You have to decide if the information given in the statements is sufficient for answering the problem. Indicate your answer as (a) if the data in the statement I alone is sufficient to answer the question; (b) if the data in the statement II alone is sufficient to answer the question; (c) if the data either in I or II alone are sufficient to answer to question; (d) if the data even in both the statements together are not sufficient to answer the question; (e) if the data in both the statement together are needed.

Statement I is merely an interpretation of the information contained in the question.
However, Senthil's salary can be determined from Statement II as follows: Let Senthil's and Javed's salaries be 4x and 4x respectively.
Then 3x=4500 or x= 1500.
Therefore Senthils salary 6000.
Thus II alone is sufficient.
