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 ratio of the students having finance as specialisation to students having HR as specialisation?

A. 11 : 19

B. 18 : 13

C. 6 : 7

D. 4 : 7

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 ratio \\ = Finance : HR \\ = \frac{960}{1120} \\ = \frac{6}{7} \\ = 6 : 7 \end{aligned}
