A Only II

B Only II and III

C Only I and II

D Only I and III

E All I, II and III

ANS:E - All I, II and III

Explanation: From III, we have: Rajan's basic salary = Rs. 1550. From I, we have: Vasu's basic salary = Rs. (1550 + 100) = Rs. 1650. From II, we have: Rajan's other allowances = Rs. 2000 and Vasu's other allowances = Rs. 2050. Therefore Vasu's monthly salary = Rs. (1650 + 2050) = Rs. 3700.
