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

Rs. 14400
Rs. 24000
Rs. 1200
Rs. 2000

Correct Answer: Rs. 14400

Explanation:

Let the monthly salary of A, B, C be Rs. 2x, Rs.3x and Rs. 5x respectively.
Then, 5x - 2x = 1200
∴ x = 400
∴ B's monthly salary = 3x = Rs. 1200
Hence, B's annual salary = Rs. (12 x 1200)= Rs. 14400
