Explanation:

Average number of female workers in all the given companies in 2013 = 156
Total female workers = 156 * 5 = 780
So the female workers in Company E in 2013 = 780 – 644 = 136
Average number of male workers in all the given companies in 2016 = 156-10 = 146
So total male workers = 146 * 5 = 730
The male workers in Company E in 2016 = 730 – 590 = 140
Difference = 140 – 136 = 4

Hence, option 4 is the correct answer.
