Show Answer

Correct Answer: (4)

Solution: (4)

Department $A \Rightarrow$ Male : Female $=1.2=\frac{12}{10}=6: 5$

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 $=(100+64+30+60+100)-(120+80+30+30+90)$ $=354-350=4$
