Answer 2

The provisions lasted for 22 days.

Explanation:

There is an inverse relation between number of students and the number of days it will take to end the provision.

Let N = number of students

D = number of days

Then , $N_1D_1=N_2D_2$

Put $N_1=550,\ D_1=28,\ \ , N_2=700$ , we gte

$550\times28=700\times D_2\\\\ D_2=\dfrac{550\times28}{700}\\\\ D_2=22$

Hence, the provisions lasted for 22 days.
