The correct option is 850.

Let us break down the given information step-by-step to find the total number of employees (male + female) in both companies Y and Z.

Step 1: Find the number of male employees in Company Z.
We are given that:
Number of male employees in Company Y = 250
Total number of male employees in both companies (Y + Z) = 400

$\text{Male employees in Z}=400-250=150$

Step 2: Find the number of female employees in Company Y.
The problem states that the number of male employees in Company Z is equal to the number of female employees in Company Y.

$\text{Female employees in Y}=\text{Male employees in Z}=150$

Step 3: Find the number of female employees in Company Z.
The number of female employees in Company Z is double the number of female employees in Company Y.

$\text{Female employees in Z}=2\times 150=300$

Step 4: Calculate the total number of employees in both companies.
Now, let us calculate the total employees (male + female) for each company:

Total employees in Company Y:
$\text{Total (Y)}=250\text{(males)}+150\text{(females)}=400$

Total employees in Company Z:
$\text{Total (Z)}=150\text{(males)}+300\text{(females)}=450$

Finally, the total number of employees in both companies combined is:

$\text{Grand Total}=400+450=850$

Therefore, the total number of employees in both companies is 850.
