  1. Step-by-step explanation:

    Food available= 400 x 30 =12,000- units.

    Number of units of food left after 20- days = 12,000-(400 x 20) = 4000.

    Number of days the food will be available for the remaining (400–200)= 200- students= 4000/200= 20- days.

    So the food will last for (20+20–30)= 10- more days.
