Question

A hostel spends 3200 on food for
20 students for 30 days. If they spend
Rs. 2400 for 30 students, for how many days
will the food last?​

Answer 1

Rs 3200 for 20 students for 30 days

so,

3200÷20×30 = 16/3 rs per day

for Rs 2400 for 30 students. let the no. of students be X

so,

16/3 = 2400/30×X

So, X = 15 days

ans. food will last for 15 days
