Answer: Option B

Solution(By Examveda Team)

Number of students in various specialisations:
$$\eqalign{ & \text{IB → } \frac{19}{100}\times8000 = 1520 \cr & \text{IR → } \frac{16}{100}\times8000 = 1280 \cr & \text{Finance → } \frac{12}{100}\times8000 = 960 \cr & \text{Marketing → } \frac{22}{100}\times8000 = 1760 \cr & \text{IT → } \frac{17}{100}\times8000 = 1360 \cr & \text{HR → } \frac{14}{100}\times8000 = 1120 \cr} $$

$$\eqalign{ & \text{Required percentage} \cr & = \left(\frac{1520}{1760}\times100\right)\% \cr & = \frac{950}{11}\% \cr & = 86.36\% \cr & \approx 86\% \cr} $$
