Show Answer
Correct Answer: (2)
Solution: (2) Ratio of students in all colleges A, B, C and D
$=2: 3: 3: 2$
Total students in college D
$=800$
$\therefore$ Total students in A
$=\left(\frac{800}{2}\right) \times 2=800$
$\therefore$ Number of students in History and Commerce
$=800 \times(25 \%+20 \%)$
$=\frac{800 \times 45}{100}=360$
