Correct Answer: I, II and III together

Explanation:

From III, we have : Rajan's basic salary = Rs 1550.

From II.  we have : Rajan's other allowances = RS 2000

             and Vasu's other allowances = Rs 2050.

Vasu's monthly salary is (1650 + 2050) = Rs 3700.

Thus, all the three statements are required.
