Final Answer:
The number of employees among the firm's workforce is 250.
Step-by-step explanation:
Among the given options, option 3) 250 is the correct answer. To determine this, let's denote the total number of employees as ( E ). The question states that 70% of the employees are in a certain category. We can express this as the equation ( 0.70 × E = 350 ), where 350 represents the number of employees in that category. To find the total number of employees, we need to solve for ( E ).
0.70 × = 350
E = {350}/{0.70}
E = 500
Therefore, the total number of employees is 500. Now, to find the number of employees in the specified category (70%), we multiply the total number of employees by 70%:
Number of employees in the category= 0.70 × 500
Number of employees in the category= 350
So, the correct answer is option 3) 250, representing the number of employees in the specified category among the firm's workforce.
In conclusion, by understanding the percentage relationship and applying the formula for finding a part of a whole, we determined that 70% of the firm's employees correspond to 350 individuals. The total number of employees was then calculated, leading to the final answer of 250 employees in the specified category.
Therefore, the correct option is 3:250
