Correct option is B
Solution:
Total of the number of employees hired during 2003 - 2005 = 35 + 50 + 40 = 125
Average of the number of employees hired during 2003 - 2005 = 125/3
Total of the number of employees promoted during 2003 - 2005
= 35 + 40 + 50 = 125
Average of the number of employees promoted during 2003 - 2005 = 125/3
Ratio = 125/3 : 125/3 = 1 : 1
