There are 2 different companies i.e., Y and Z. Number of male employees working in company Y is 250 and number of male employees working in company Z is equal to number of female employees working in Y . Total number of male employees in both company is 400 and number of female employees working in company Z is double to that of female employees in company Y .

Find the average number of male working in company Y and number of female working in company Z?

The correct option is 275.

Let us break down the given information step-by-step to find the required average.

Step 1: Find the number of male employees in Company Y and Company Z.

We are given that:

Number of male employees in Company Y = 250

Total number of male employees in both Company Y and Company Z = 400

Therefore, the number of male employees in Company Z is calculated as:

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

Step 2: Find the number of female employees in Company Y and Company Z.

The problem states that the number of male employees working in Company Z is equal to the number of female employees working in Company Y.

So, Number of female employees in Company Y = 150

Next, we are told that the number of female employees working in Company Z is double that of female employees in Company Y.

Therefore, the number of female employees in Company Z is:

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

Step 3: Calculate the average number of male employees in Company Y and female employees in Company Z.

We need to find the average of:

1. Male employees in Company Y = 250

2. Female employees in Company Z = 300

Using the average formula:

$\text{Average}=\frac{250+300}{2}$

$\text{Average}=\frac{550}{2}=275$

Hence, the average number of male employees working in company Y and female employees working in company Z is 275.
