Question

The average monthly salary of workers in a factory is $₹206$. If the average monthly salary of males and females are $₹210$ and $₹190$ respectively, the percentage of females employed in the factory is

• A. $10\%$
• B. $50\%$
• C. $30\%$
• D. $20\%$

Answer 1

Answer: (D)

Let number of males $=x$
and number of females $=y$
According to question, $206(x+y)=210x+190y$
$\Rightarrow 206x+206y=210x+190y$
$\Rightarrow 4x=16y$
$\Rightarrow x=4y$
So $\%$ of females employed in the factory $=\frac{y}{5y}\times 100$
$=\frac{1}{5}\times 100=20\%$
