MAT Exam 2021 Paper

Concept:For a fixed topic, the number of articles in different magazines is proportional to the pages allotted to that topic.Explanation:From Chart I, total pages in magazine C $= 168$ and in magazine B $= 275$.From Chart II, Arts form $12\%$ of the articles submitted in any magazine.Pages occupied by Arts in C:$\frac{12}{100} \times 168 = 20.16$Pages occupied by Arts in B:$\frac{12}{100} \times 275 = 33$Given: number of Arts articles in C $= 6$.Let the number of Arts articles in B be $x$.Since the number of articles is proportional to the pages occupied:$\frac{6}{x} = \frac{20.16}{33}$$\Rightarrow x = \frac{6 \times 33}{20.16}$$\Rightarrow x = 9.82 \approx 10$Therefore, the number of Arts articles in B is about 10.Answer:Option C. 10
