How many of the employees at Company X have life insurance?

Statement (1) There are 300 employees at Company X.

This statement just gives us the total number of employee at company X. There is no information on the number of employees having life insurance. Hence this statement is not sufficient.

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

This statement on gives the ratio of employees with life insurance to employees without life insurance. But there is no actual number of employees given. Hence this statement is not sufficient.

Combining both the statement we can find the number of employees at Company X having life insurance

Answer is C

Hi All,

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:

GMAT assassins aren't born, they're made,
Rich

(1) Not sufficient obviously, nothing mentioned in either numerical or percentage terms about those having insurance out of 300.

(2) 1:5
This tells us that 1/6 of total employees have life insurance, while 5/6 of total do not. But we dont know total number. Insufficient.

Combining, employees having life insurance = 1/6 * 300 = 50.

Hence C answer
