Show Answer

Answer: (2)

Solution: (2)

British passengers

$\Rightarrow \frac{1200 \times 18}{100} = 216$

Females

$\Rightarrow \frac{216}{4} = 54$ ;

Males

$\Rightarrow 216 - 54 = 162$

Passengers from Madagascar

$\Rightarrow \frac{1200 \times 6}{100} = 72 =$ Males $(∵$ females $= 0)$

Passengers from South Africa

$\Rightarrow 1200 \times \frac{2}{5} = 480$

Males

$\Rightarrow 240$

Females

$\Rightarrow 240$

Indian passengers

$\Rightarrow 1200 - 216 - 72 - 480 = 432$

Females

$\Rightarrow 432 \times \frac{2}{3} = 288$ ;

Males

Required ratio $= 72 : 240 : 432 = 3 : 10 : 18$
