Female workers in Gaming = 18\(\%\) of 20\(\%\)of \(40250 = 1449\)
\(\%\) required = \(\left( \frac{\text{Female workers in Gaming}}{\text{Total no of people working in night shifts from all industries}} \right) \times 100\)
= \(\left( \frac{1449}{40250} \right) \times 10\)
= 3.6\(\%\)
So the correct option is (B)
Total number of female workers \(= 13363\)
Total number of male workers \(= 40250 - 13363 = 26887\)
Difference between male & female workers \(= 27853 - 13363 = 13524\)
\(\%\)required \(=\left( \frac{\text{Difference between male \& female workers}}{\text{Total workers}} \right) \times 100\)
\(\%\) required = \(\frac{13524}{40250} \times 100\)
= 33.6\(\%\)
So the correct option is (C)
