The total number of employees in IT sector = 1800 $\times$ $\frac{13}{100}$= 234

Number of female employees = 1200 $\times$ $\frac{14}{100}$= 168

Number of male employees = 234 – 168 = 66.

Now total number of employees in H.R = 1800 $\times$ $\frac{12}{100}$ = 216

Number of female employees = 1200 $\times$ $\frac{14}{100}$ = 168

Number of male employees = 216 – 168 = 48.

The total number of employees in finance sector = 1800 $\times$ $\frac{20}{100}$ =360

Number of female employees = 1200 $\times$ $\frac{30}{100}$ = 360

Number of male employees = 360 – 360 =0
