In an office of 900 employees, on a particular day, except for 10% of the female employees, all employees were present. On the next day, except for 8% of the male employees, all employees were present. The number of employees present on each of these two days was the same. Find the total number of male employees on the payrolls of this office.

500

According to question ,

10% of female employee = 8% of male employee

So , Ratio of female employee to male employee = 4 : 5

Now , 9R = 900

1R = 100

5R = 500

So , Number of male employee = 500
