What is the total number of students having specialization in IR, Marketing, and IT?


A) 4640

B) 4080

C) 4260

D) 4400

Answer:

Option D

Explanation:

Number of students in various specializations:

IB → $\left(\frac{19}{100}\times8000\right)$ = 1520

IR → $\left(\frac{16}{100}\times8000\right)$ = 1280

Finance → $\left(\frac{12}{100}\times8000\right)$ = 960

Marketing → $\left(\frac{22}{100}\times8000\right)$ = 1760

IT → $\left(\frac{17}{100}\times8000\right)$ = 1360

HR → $\left(\frac{14}{100}\times8000\right)$ = 1120

Required number of students = (1280 + 1760 + 1360) = 4400.
