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.

Students having IB as specialisation forms approximately what percent of students having Marketing as specialisation?

A. 116%

B. 86%

C. 124%

D. 74%

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}

\begin{aligned} Required percentage \\ = (\frac{1520}{1760} \times 100) % \\ = \frac{950}{11} % \\ = 86.36 % \\ \approx 86 % \end{aligned}
