Answer: Option B
Solution(By Examveda Team)
Number of male athletes in 2006 from C= 6.9 × 100
= 690
Number of male athletes in 2007 from C
= 4.8 ×100
= 480
$$\eqalign{ & \therefore \text{Decrease }\% \cr & = \left(\frac{690-480}{690}\times100\right)\% \cr & = \left(\frac{210}{690}\times100\right)\% \cr & = \frac{700}{23} \% \cr & = 30.4\% \cr & \approx 30\% \cr} $$
