1)

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 ?


A) 21%

B) 30%

C) 35%

D) 39%

E) 25%

Answer:

Option B

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).
