Question

A hostel had rations for 150 students for 60 days. After 12 days, 30 more students join the hostel. How long will the remaining rations last?​

Answer 1

Answer:

Step-by-step explanation:

for 150 students the ration lasted for =60 days

after 12 days the ratio would last for= 60-12

48 days

now, for 150 students the ration lasts for= 48days

for one student the ration will last for= 48×150

if 30 more join the ration would last for= 48×150/180

=40 days

Answer 2

The remaining rations will last for 40 days.

Given : A hostel had rations for 150 students for 60 days. And, after 12 days, 30 more students join the hostel..

To find : The number of days for which the remaining rations will last.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the required number of days)

Here, we will be using the general arithmetic method.

As, 12 days had already been passed, 150 students have rations for = 60-12 = 48 days

And, total students after addition of new students = (150+30) = 180

So,

150 students have rations for = 48 days

1 student has rations for = (150 × 48) days

180 students have rations for = (150×48)/180 = 40 days

(This will be considered as the final result.)

Hence, the remaining rations will last for 40 days.
