Question: Vinod's and Javed's salaries are in the proportion of 4 : 3 respectively. What is Vinod's salary? Statements: Javed's salary is 75% that of Vinod's salary. Javed's salary is Rs 4500.

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient
Both I and II are sufficient

Correct Answer: II alone is sufficient while I alone is not sufficient

Explanation:

Statement I is merely an interpretation of the information contained in the question.

However, Vinod's salary can be ascertained from II as follows : Let Vinod's and Javed's salaries be 4x and 3x respectively. Then, 3x = 4500 or x = 1500. Therefore Vinod's salary = 4x = Rs. 6000.
