The average salary of all employes of a company is Rs. `5000`. The average salary of male is Rs. `5200` and the average salary of female is Rs. `4200`. How much percentage of male are in the company?

Answer

To solve the problem, we will use the method of alligation to find the percentage of male employees in the company.

### Step-by-Step Solution:

1. **Identify the Given Data:**
- Average salary of all employees (A) = Rs. 5000
- Average salary of male employees (M) = Rs. 5200
- Average salary of female employees (F) = Rs. 4200

2. **Set Up the Alligation:**
- We will use the alligation formula to find the ratio of male to female employees.
- The formula for alligation is:
\[ \text{Ratio of Male to Female} = \frac{F - A}{M - A} \]

3. **Calculate the Differences:**
- Calculate \(F - A\):
\[ F - A = 4200 - 5000 = -800 \]
- Calculate \(M - A\):
\[ M - A = 5200 - 5000 = 200 \]

4. **Set Up the Ratio:**
- Now we can set up the ratio:
\[ \text{Ratio of Male to Female} = \frac{-800}{200} \]
- Since we are interested in the absolute values for the ratio:
\[ \text{Ratio of Male to Female} = \frac{800}{200} = 4 \]

5. **Express the Ratio:**
- This means for every 4 males, there is 1 female. Hence, the ratio of males to females is 4:1.

6. **Calculate the Total Parts:**
- Total parts = 4 (males) + 1 (female) = 5 parts.

7. **Calculate the Percentage of Males:**
- Percentage of males in the company:
\[ \text{Percentage of Males} = \left(\frac{\text{Number of Males}}{\text{Total Employees}}\right) \times 100 = \left(\frac{4}{5}\right) \times 100 = 80\% \]

### Final Answer:
The percentage of males in the company is **80%**.
