What was the average number of female athletes who participated from country B over all the years together?
Discuss
Answer & Solution
Average number of female athletes from B over all the years.
$$\eqalign{ & = \frac{\left(4.2+6.2+4.8+8.4+5.2+7.2\right)\times100}{6} \cr & = \frac{3600}{6} \cr & = 600 \cr} $$
2
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?
Discuss
Answer & Solution
Number of female athletes from E in 2009
= 9.2 × 100
= 920
Total number of athletes from B in 2008
= (11.4 + 8.4) × 100
= 19.8 × 100
= 1980
Let 920 = x% of 1980
Then,
$$\eqalign{ & \Rightarrow \frac{x}{100}\times1980 = 920 \cr & \Rightarrow x = \frac{920 × 100}{1980} \cr & \,\,\,\,\,\,\,\,\, = \frac{4600}{99}\% \cr & \,\,\,\,\,\,\,\,\, = 46.46\% \cr & \,\,\,\,\,\,\,\,\, \approx 46\% \cr} $$
3
In which of the following years was total number of participates (athletes) the second highest from Country C?
Discuss
Answer & Solution
Total number of athletes from C in various years:
2005 → (4.5 + 3.1) × 100
            = 7.6 × 100
            = 760
2006 → (6.9 + 3.3) × 100
            = 10.2 ×100
            = 1020
2007 → (4.8 + 2.8) × 100
            = 7.6 × 100
            = 760
2008 → (6.6 + 4.2) × 100
            = 10.8 × 100
            = 1080
2009 → (7.9 + 6.3) × 100
            = 14.2 × 100
            = 1420
2010 → (10.8 + 6.9) × 100
            = 17.7 × 100
            = 1770
It was second highest in 2009. So, the correct answer is (E).
4
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?
Discuss
Answer & Solution
  Number of male athletes in 2006 from C
  = 6.9 × 100
  = 690
  Number of male athletes in 2007 from C
  = 4.8 ×100
  = 480
$$\eqalign{ & \therefore \text{Decrease }\% \cr & = \left(\frac{690-480}{690}\times100\right)\% \cr & = \left(\frac{210}{690}\times100\right)\% \cr & = \frac{700}{23} \% \cr & = 30.4\% \cr & \approx 30\% \cr} $$
