Hi swerve,

We're asked for the number of employees at Company X that have life insurance.

1) There are 300 employees at Company X.

Fact 1 gives us the total number of employees, but still don't know the exact number who have life insurance.
Fact 1 is INSUFFICIENT

2) The ratio of employees with life insurance to employees without life insurance is 1:5.

Fact 2 tells us that for every 6 employees, 1 of the 6 has life insurance. However, we don't know the total number of employees who actually have life insurance.
Fact 2 is INSUFFICIENT

Combined, we know the total number of employees (300) and the fraction that have life insurance (1/6), so we CAN calculate the total number of employees who have life insurance (1/6 of 300 = 50).
Combined, SUFFICIENT

Final Answer: C
