Given:

Number of employees in sector Q = 850

Number of employees in sector S = 900

Ratio of male to female employees in sector Q = 11 : 6

Ratio of male to female employees in sector S = 4 : 5

Calculations:

Let the number of males and females in sector Q be 11x and 6x, respectively.

Let the number of males and females in sector S be 4y and 5y, respectively.

The total number of employees in sector Q = 850

11x + 6x = 850

⇒ 17x = 850

⇒ x = 850 / 17 = 50

Number of males in sector Q = 11x = 11 × 50 = 550

The total number of employees in sector S = 900

4y + 5y = 900

⇒ 9y = 900

⇒ y = 900 / 9 = 100

Number of females in sector S = 5y = 5 × 100 = 500

Total number of males from sector Q and females from sector S:

550 (males from sector Q) + 500 (females from sector S) = 1050

∴ The total number of males from sector Q and females from sector S is 1050.
