Answer 1

Answer= let number of boys out of hostel be X

Now,500=4 so the difference is 125

Now, 125*20=2500 ,, hence the X = 2500

Answer 2

boys-500. x2

days-4. 20

direct varitation-

$\frac{x1}{y1} = \frac{x2}{y2} \\ \frac{500}{4} \times \frac{20}{x2} \\ = 2500$

2500 students have gone out of hostel.
