Let's assume the number of employees who take the bus to work is 2x, where x is a positive constant.
According to the given information, the ratio of employees who take the bus to work to those who drive to work is 2:5. Therefore, we can write the equation:
(2x) / 120 = 2 / 5
To solve for x, we can cross-multiply:
5 * (2x) = 2 * 120
10x = 240
Dividing both sides by 10:
x = 240 / 10 = 24
So, the number of employees who take the bus to work is 2x = 2 * 24 = 48.
To find the total number of employees at the factory, we can sum the number of employees who take the bus and those who drive:
Total employees = Employees who take the bus + Employees who drive
Total employees = 48 + 120 = 168
Therefore, there are 168 employees working at the factory.
The correct answer is B. 168.
