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
=3×400
=1200
B's annual salary:
=1200×12
=14400
Therefore, B's annual salary is Rs. 14,400.
The answer is option 2.
