The monthly salary of A, B and C are in the ratio 2 : 3 : 5. If C's monthly salary is Rs.1200 more than that of A, then B's annual salary is:

Rs. 14400

The correct answer is Option (2) → Rs. 14400

Let the monthly salaries of A, B, and C be 2x : 3x : 5x.

Given:
C’s salary − A’s salary = 1200
⇒ 5x - 2x = 3x = 1200
⇒ x = 400

So,
B’s monthly salary = 3x = 3 × 400 = ₹1200

B’s annual salary = 1200 × 12 = ₹14,400
