Answer 1

Answer:

30 days

Step-by-step explanation:

According to the given condition:

After 12 days, the ration is sufficient for 500 students for (16 - 12) = 48 days.

Given that after 12 days, 300 more students join the hostel.

So, number of students in the hostel = 500 + 300

                                                             = 800.

Since for 500 students, ration is sufficient for 48 days.

For 1 students, ration is sufficient for (500 * 48) days.

∴ For 800 students, the ration is sufficient for (500 * 48)/800

⇒ 30 days.

Therefore, the remaining rations last for 30 days.

Hope it helps!

Answer 2

Answer:

30

Step-by-step explanation:

the total ration is the product of the days and students.

total ration = 60*500 = 30000

in 12 days, the ration completed = 12*500 = 6000

remaining ration = 30000-6000 = 24000

additional students = 300

now, total students = 500+300 = 800

now, to find the number of days the remaining ration will last, we modify the above formula as

d = 24000/800 = 30 days

the remaining ration will last 30 days.
