Data Sufficiency (DS) | Re: A certain company currently has how many employees?

Let number of employees in company = x

1) if 4 employee added number will be "atleast" 30

x+4 >= 30 => x>=26

Not Sufficient

2) if 4 employee resign number will be "fewer than" 23

x-4 < 23 => x < 27

Not Sufficient

1+2

x>=26 and x<27

Therefore x=26

Answer: C
