Answer 1

Answer:

45 days

Step-by-step explanation:

100 is 1/2 of 200 so if 200 stu takes 30 days so 200+100=300 stu takes 45 days

Answer 2

Answer:

If 100 new students join, then the provision will last for 20 days.

Step-by-step explanation:

A mess has provision for 200 students for 30 days

More the number of students, less the duration the provision will last.  That is, the Number of students and duration the provision lasts are inversely proportional.

∴ $\frac{Student Number 1}{Student Number 2} = \frac{Duration Last 2}{Duration Last 1}$

$=>\frac{200}{200+100} = \frac{Duration Last 2}{30}$

$=>Duration Last 2 = 30 . \frac{200}{300} days = 20 days$
