Question

• A. 2:5:18
• B. 3:10:18
• C. 3:11:18
• D. 2:18:5
• E. None of these

Answer 1

The correct option is B

3:10:18

British passengers :
Total $=\frac{1200\times 18}{100}=216$
Females $=\frac{216}{4}=54$
Males $=216-54=162$

Passengers from Madagascar :
Total $=\frac{1200\times 6}{100}=72=$Males

Passengers from South Africa :
Total $=1200\times \frac{2}{5}=480$
Males = 240
Females = 240

Indian passengers:
Total = 1200 – 216 – 72 – 480 = 432
Females = $432\times \frac{2}{3}$ = 288
Males = 432 – 288 = 144

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