1. Study the pie-chart given below carefully and answer the questions that follow.
Percentage-wise break up of students in terms of specialization in M.B.A.
Total Number of students = 8000.

What is the total number of students having specialisation in IR, marketing and IT?

A. 4640

B. 4080

C. 4260

D. 4400

Solution:

Number of students in various specialisations:

\begin{aligned} IB → \frac{19}{100} \times 8000 = 1520 \\ IR → \frac{16}{100} \times 8000 = 1280 \\ Finance → \frac{12}{100} \times 8000 = 960 \\ Marketing → \frac{22}{100} \times 8000 = 1760 \\ IT → \frac{17}{100} \times 8000 = 1360 \\ HR → \frac{14}{100} \times 8000 = 1120 \end{aligned}

Required number of students
= 1280 + 1760 + 1360
= 4400
