Question

a hostel spends 3200 on food for 20 students for 30 days if they spends 2404 30 students for how many days will the food last​

Answer 1

Answer:

Money spent on 20 students for 30 days = Rs.3200

Therefore, money spent on 1 student for 30 days => Rs.3200/20 = Rs.160

Now, money spent on 1 student for 1 day => Rs.160/30 = Rs.16/3

Now,money used for 30 students => Rs.16/3 ×30 =Rs.160

Let, the number of days the food will last be x.

Therefore, number of days food will be left => Rs.160 × x = Rs.2400

=> x = Rs.2400/Rs.160

=> x = 15 days

The food will last for 15 days.
