Question

The ratio of the numbers of male and female workers in a textile mill is $5:3$. If there an $115$ male workers, what is the number of female workers in the mill?

Answer 1

Let the common multiple be $x$

Number of males $=5x$

Number of females $=3x$

According to the given condition,

$5x=115$

$x=23$

Therefore, number of female workers

$=3x$

$=3\times 23$

$=69$

Hence, this is the answer.
