 In which of the following countries is the difference between the number of male and female participants

 second highest in the year 2006?

Answer:

Explanation:

In 2006, the difference between males and females in various countries was

A → (6.6 - 4.2) x 100 = (2.4 x 100) = 240;

B → (8.4 - 6.2) x 100 = (2.2 x 100) = 220;

C → (6.9 - 3.3) x 100 = (3.6 x 100) = 360;

D → (8.4 - 6.3) x 100 = (2.1 x 100) = 210;

E → (7.8 - 5.2) x 100 = (2.6 x 100) = 260.

It was second highest in E.

The number of female athletes who participated from Country E in the year 2009 was approximately what percentage of the total number of athletes who participated from Country B in the year 2008 ?

Answer:

Explanation:

Number of female athletes from E in 2009 = (9.2 x 100) = 920.

Total number of athletes from B in 2008 = (11.4 + 8.4) x 100 = 19.8 x 100 = 1980.

Let 920 = x % of 1980. Then,

$\frac{x}{100}\times1980 = 920 \Rightarrow x$

= $\frac{920\times100}{1980}$

= $\frac{4600}{99}$% = 46.46% = 46%.

What was the approximate percentage decrease in the number of male athletes who participated from Country C in the year 2007 as compared to the previous year ?

Answer:

Explanation:

Number of male athletes in 2006 from C = (6.9 x 100) = 690.

Number of male athletes in 2007 from C = (4.8 x 100) = 480.

Decrease % = $\frac{\left(690-480\right)\times100}{690}$%

= $\frac{210}{690}\times100$% = $\frac{700}{23}$% = 30.4% = 30% (nearly).

What was the average number of female athletes who participated from Country B over all the years together?

Answer:

Explanation:

Average number of female athletes from B over all the years

= $\frac{\left(4.2+6.2+4.8+ 8.4 + 5.2 +7.2\right)\times100}{6}$

= $\frac{3600}{6}$ = 600

In which of the followinlg years was the total number of participants (athletes) the second highest from Country C?

Answer:

Explanation:

Total number of athletes from C in various vears:

2005 → (4.5 + 3.1) x 100 = (7.6 x 100) = 760;

2006 → (6.9 + 3.3) x 100 = 10.2 x 100 =1020;

2007 → (4.8 + 2.8) x 100 = (7.6 x 100) = 760;

2008 → (6.6 + 4.2) x 100 = 10.8 x 100 = 1080;

2009 → (7.9 + 6.3) x 100 = 14.2 x 100 = 1420;

2010 → (10.8 + 6.9) x 100 = 17.7 x 100 =1770.

It was second highest in 2009. So, the correct answer is (e)
