Answer:
Correct Answer; C
Solution:
- (c) Total number of students from country B $\Rightarrow $ $\frac{9000 \times 14}{100}=1260 $ Female students $\Rightarrow $ $\frac{3500 \times 14}{100}=490 $ Male students $\Rightarrow $ $ 1260-490 =770 $ Total number of students from country C $\Rightarrow $ $\frac{9000 \times 7}{100}=630 $ Female students $\Rightarrow $ $\frac{3500 \times 10}{100}=350 $ Male students $\Rightarrow $ $ 630-350 =280 $ $\therefore $ Required ratio $ =( 770280 ):( 1260630 ) $ $ =1050:1890 =5:9 $
