The total monthly salary of all the employees in a company is rs 75000. To determine what is the total number of employees in that company? Which of the following information given in A and B are sufficient
A .40 employees get rs 1000 per month
B. `20%` of the employees get rs 2000 per month.

Options

A. IF I alone is sufficient
B. If II alone is sufficient
C. I and II together are not sufficient
D. Neither I isneeded nor II is neede

Answer

To determine the total number of employees in the company based on the given information, we will analyze both pieces of information (A and B) separately and then together.

### Step 1: Analyze Information A
**Given:** 40 employees get Rs 1000 per month.

- Calculate the total salary paid to these 40 employees:
\[ \text{Total Salary from A} = 40 \times 1000 = 40000 \text{ Rs} \]

- Now, subtract this from the total monthly salary of all employees:
\[ \text{Remaining Salary} = 75000 - 40000 = 35000 \text{ Rs} \]

- Let \( x \) be the total number of employees in the company. The remaining employees can be calculated as:
\[ \text{Remaining Employees} = x - 40 \]

- We need to know the salary of these remaining employees to find \( x \). Since we do not have that information from A alone, we cannot determine the total number of employees using only information A.

### Step 2: Analyze Information B
**Given:** 20% of the employees get Rs 2000 per month.

- Let \( x \) be the total number of employees. Then, 20% of \( x \) is:
\[ \text{Number of Employees getting Rs 2000} = 0.2x \]

- The total salary paid to these employees is:
\[ \text{Total Salary from B} = 0.2x \times 2000 = 400x \]

- The remaining salary paid to the other employees is:
\[ \text{Remaining Salary} = 75000 - 400x \]

- The remaining employees would be:
\[ \text{Remaining Employees} = x - 0.2x = 0.8x \]

- To find the total number of employees, we need to know the salary of the remaining employees, which is not provided in B alone. Thus, we cannot determine the total number of employees using only information B.

### Step 3: Combine Information A and B
Now, let's combine both pieces of information to see if we can find \( x \).

From Information A:
- We have 40 employees earning Rs 1000, contributing Rs 40000 to the total salary.

From Information B:
- We have 20% of \( x \) employees earning Rs 2000, contributing Rs 400x to the total salary.

Combining these:
\[ 40000 + 400x + \text{Salary of remaining employees} = 75000 \]

Let the remaining employees earn \( y \) Rs per month. We can express the remaining salary as:
\[ \text{Remaining Salary} = 75000 - 40000 - 400x \]

However, without knowing the salary of the remaining employees, we cannot solve for \( x \) directly.

### Conclusion
Neither A nor B alone is sufficient to determine the total number of employees, and even when combined, we still lack information about the salary of the remaining employees.

### Final Answer
Neither A nor B is sufficient alone, and together they are also insufficient to determine the total number of employees.
