What is the respective ratio of the number of women working in the HR department of the organisation and the total number of employees in that department? |
A) 3 : 4
B) 2 : 5
C) 2 : 9
D) 3 : 7
E) None of these
Correct Answer: A
Solution :
Let number of men and women working in HR department be x and 3x, respectively. |
Then, \[x+3x=14\]% of 1800 |
\[\Rightarrow \] \[4x=252\] |
\[\Rightarrow \] \[x=63\] |
\[\therefore \] Number of women in HR department |
\[=3\times 63=189\] |
\[\therefore \] Total number of employees in HR department = 252 |
\[\therefore \] Required ratio = 189: 252 = 3: 4 |
