Explanation:

15/100 * total people in company = 375
So total people in company= 2500
And total people in department F is 20/100 * 2500 = 500
Let total number of employees in dept D below 40 years is x and above 40 years is y. Then
1/10 * y + 3/10 * x = 122 or
3x + y = 1220
Also from above total people in department F is 500 so
x + y = 500
Solve the two equations, x = 360
So number of males below 40 years in department F = 7/10 * 360 = 252
