Question

What is the average number of male passengers from all the four countries?

• A. 154.5
• B. 164.5
• C. 145
• D. 164
• E. None of these

Answer 1

The correct option is A

154.5

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

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

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

$\therefore$ Average number of male passengers $=\frac{162+72+240+144}{4}=\frac{618}{4}=154.5$
