1. The data given in bar diagram relate to the department wise admission of 320 students to B Sc. (Honors) first year classes of a certain college in the given five subjects. Study the graph and answer the questions.

The total number of male students who got admitted in mathematics and economics as compared to the total number of female students getting admission in mathematics and economics is:

A. More by 4.2%

B. More by 12.8%

C. More by 14.8%

D. Less by 17%

Solution:

Total number of male students in Mathematics and Economics
= 30 + 32
= 62
Total number of female students in Mathematics & Economics
= 20 + 34
= 54
∴ Required %

\begin{aligned} = \frac{62 - 54}{54} \times 100 \\ = \frac{8}{54} \times 100 \\ = \frac{400}{27} % \\ = 14.8 % more \end{aligned}
