What is the total monthly salary of Vasu ?
Statements:
1. Vasu's basic salary is Rs 100 more than Rajan's salary who also serves in Vasu's company.
2. Other allowances drawn by Rajan besides his basic salary are Rs 2000 per month which is Rs 50 less than Vasu's salary.
3. Rajan's basic salary is Rs 1550 per month,

From 3, we have: Rajan's basic salary = Rs. 1550.
From 1, we have: Vasu's basic salary = Rs. (1550 + 100) = Rs. 1650.
From 2, 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.
