Question

The mean monthly salary paid to all employees in a certain company was ₹ 600. The mean

monthly salaries paid to male and female employees were ₹ 620 and ₹ 520 respectively. Find the

percentage of male and female employees in the company.

Answer 1

Let there be x males and y females
(620x+520y)/x+y=600
620x+520y=600x+600y
20x=80y
X=4Y
Percentage of males = (4y/5y)×100=80%
And percentage of females =20%

Answer 2

Answer:

The percentage of males is 80 %,

And, the percentage of females is 20%.

Step-by-step explanation:

Let x be the numbers of males and y be the numbers of females,

Since, the average monthly salary of males = 620

⇒ Total sum of the monthly salary of males = 620 x

Similarly, total sum of the monthly salary of females = 520 y,

Hence, the total sum of the salaries = 620x + 520y

Now, the average salary of both males and females = ₹ 600

⇒ The total sum of their salaries = 600(x+y)

⇒ 600(x+y) = 620x + 520y

⇒ 80y = 20x

⇒ 4y = x

Hence, the total males and females = x + y = 4y + y = 5y,

Percentage of males = 4y/5y × 100 = 80 %,

And, the percentage of males = y/5y × 100 = 80 %
