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. 24000

Rs. 14400

Rs. 12000

Rs. 96000

✅ Correct Option: 2

The monthly salaries of A, B and C are in the ratio 2:3:5.

C's monthly salary is Rs.1200 more than A's monthly salary.

Let each part of the ratio equal $x$ .

A's monthly salary $= 2x$

B's monthly salary $= 3x$

C's monthly salary $= 5x$

C's salary is Rs.1200 more than A's salary:

$5x = 2x + 1200$

$5x - 2x = 1200$

$3x = 1200$

$x = 400$

B's monthly salary:

$= 3x$

$= 3 \times 400$

$= 1200$

B's annual salary:

$= 1200 \times 12$

$= 14400$

Therefore, B's annual salary is Rs. 14,400.
