ratio

(1) A ratio of 16/9 can be achieved with a lot of number combinations, it´s usells info to reacho a number for female employees

(2) Is only a comparation, so it can´t be used to get an absolute value.

Using the info from (1) and (2) we can construct the following equation:

(x+105)/x=16/9, that will eventually give x=169, so there are 169 female employees in X.

C is the answer

m->males
f->females

Stmt I

m / f+14 = 16/9

9m = 16f + 16*14

INSUFF (2 variables i equation)

Stmt I

m = f+105

m and f could take on multiple values satisfying this condition

INSUFF

Together

9m = 16f + 16*14 (1)
m = f+105 (2)

Substitute m from (2) in (1) and it can be solved

SUFF

C)

IMO C


Male/ female+ 14 = 16/9 --- from first

Male - Female = 105 ----- from second

Solve both the equations:
