The average monthly salary of all the employees in an industry is 12000 Rs. The average salary of male employees is 15000 Rs. and that of female employees is 8000 Rs. What is the ratio of male employees to female employees?
[A]2 : 5
[B]3 : 4
[C]4 : 3
[D]5 : 2

4 : 3
Let, Male employees = x and Female employees = y
∴ (x + y) 12000 = x \times 15000 + y \times 8000
=> (x + y) \times 12 = 15x + 8y
=> 12x + 12y = 15x + 8y
=> 3x = 4y
=> \frac{x}{y} = \frac{4}{3}
=> x : y = 4 : 3
Hence option [C] is correct answer.
