Description for Correct answer:
Let the number of qualified candidates in year 2006 =x
The number of qualified candidates in year 2008 = \( \large \frac{480 \times 60}{100} = 288 \)
According to question, x + 288 =2 x 249
= > x=498 -288
= > x=210
Percentage of appeared candidates who qualified in 2006 = \( \large \frac{210}{700} \times 100 = 30% \)
