C) 390
D) 440
E) None of these
Correct Answer: B
Solution :
| As there are 1049 students in Arts which constitutes 23% of total students by faculty. |
| Let the total number of students in the university be x. |
| \[\therefore \] 23% of \[x=1049\] |
| \[\Rightarrow \]\[\frac{23\times x}{100}=1049\] |
| \[\Rightarrow \]\[x=\frac{1049\times 100}{23}\approx 4560\] |
| \[\therefore \]Total students \[=4560\] |
| Percentage of engineering students \[=9%\] |
| \[\therefore \]Total number of engineering students |
| \[=9\times \frac{4560}{100}\approx 410\] |
