Answer:

Correct Answer: B

Solution:

  • Let the number of men and women in production department be 11x and x, respectively. Then, $ 11x+x=28 $ % of 1800

$ \Rightarrow $ $ 12x=504 $
$ \Rightarrow $ $ x=42 $

$ \therefore $ Number of men in Production department $ =11\times 42=462 $ Total number of employees in Production department = 504

$ \therefore $ Required percentage $ =\frac{462}{504}\times 100\approx 91.67 $ %
