Solution :
The number of employees currently in a company = 268
Percentage of employees less than a year ago = 33%
Let he number of people a year ago = x
∴ At present the number of employees = [tex]$x - x \times \frac{33}{100}$[/tex]
  ⇒ 268 = x (1 - 0.33)
  ⇒ 268 = 1x -0.33 x
  ⇒ 268 = 0.67 x
  ⇒ x = 400
Number of employees in a year is = 400
