percent increase = (percent change/original ) * 100%
= ((60% - 20%)/20%) * 100%
= 200%
Hence, D.

This question is about % change.
Formula : (new rate - old rate ) / old rate
Let assume the number of employees be 100.
1994 : 20
1998 : 60
Change in Number = 40
So,
(40 / 20) * 100
= 200 %
Thus the best answer is D.
