Answer» Answer: students, for 45 days supply = Total units is 6,750. 150 students for 10 days = 1,500 units USED, therefore food balance is now reduced down to 5,250 units 5,250 units divided by 125 students (after 25 leave) = 42 Answer: Food supply will last for 42 days based on 125 students Lets SAY a RATION is what one student eats in a day. To start we have 150 * 45 = 6750 rations. During 10 days 150 students use 1500 rations, so 5250 rations are left. Now the remaining rations are shared by only 125 students, so the food lasts for 5250 / 125 = 42 days. The food will last for 52 days, or 7 extra days.

Answer:

students, for 45 days supply = Total units is 6,750.

150 students for 10 days = 1,500 units USED, therefore food balance is now reduced down to 5,250 units

5,250 units divided by 125 students (after 25 leave) = 42

Answer: Food supply will last for 42 days based on 125 students

Lets SAY a RATION is what one student eats in a day.

To start we have 150 * 45 = 6750 rations.

During 10 days 150 students use 1500 rations, so 5250 rations are left.

Now the remaining rations are shared by only 125 students, so the food lasts for 5250 / 125 = 42 days.

The food will last for 52 days, or 7 extra days.
