• C. $30,70$
• D. $70,30$

Answer 1

The correct option is A $80,20$

Given, the mean annual salary of all employees in a company is $Rs25,000$ & mean salaries of male and female employees are $Rs27,000$ and $Rs17,000$ respectively.

Let us consider mean salaries of male as $Rs.27000$ and female as $17,000$

$\frac{27,000x+17,000y}{x+y}=25,000$

$27,000x+17,000y=25,000x+25,000y$

$2000x=8000y$

$x=4y$

Percentage of males $\left(4y/5y\right)\times 100=80\%$

Percentage of females $=20\%$
