Question

A hostel spends 5000 as cost of sugar for 30 students for 25 days. If they spend 4000 for 40 students,
for how many days will the sugar last?​

Answer 1

Answer:

15 days

Step-by-step explanation:

The hostel spends 5000 for 30 students for 25 days

i.e it spends 5000/25=200 per day for 30 students

So if 200 is spent on 30 students

The money spent on 1 student will be 200/30........(1)

Now the number of students are 40

So from (1) we can say that the amount spent per day on 40 students will be

40×(200/30).........(2)

Let this amount be spent for x days

So total amount spent will be

x×40×(200/30)=4000 ( given)

x= (4000×30)/(40×200)

x=15

So the sugar will last for 15 days
