Correct Answer: (4)
Solution: (4) Department $A \Rightarrow$ Male : Fe-
male $=1.2=\frac{12}{10}=6: 5$
Sum of the terms of ratio
$=6+5=11$
Number of males
$=\frac{6}{11} \times 220=120$
Number of females
$=220-120=100$
Department $B \Rightarrow$ Male : Female $=5: 4$
$\therefore \quad$ Males $\Rightarrow \frac{5}{9} \times 144=80$
Females $\Rightarrow \frac{4}{9} \times 144=64$
Department $C \Rightarrow$ Male : Female $=1: 1$
$\therefore \quad$ Males $\Rightarrow \frac{1}{2} \times 60=30=Fe-$ males
Department $D \Rightarrow$ Male : Female $=1: 2$
$\therefore \quad$ Males $\Rightarrow \frac{1}{3} \times 90=30$
Females $\Rightarrow 60$
Department $E \Rightarrow$ Male : Female $=9: 10$
Males $\Rightarrow \frac{9}{19} \times 190=90$
Females $\Rightarrow 100$
Required difference $=$
$(100+64+30+60+100)-$
$(120+80+30+30+90)$
$=354-350=4$
