A hotel spends rupees 3200 on food for 20 students for 30 days . If they spend rupees 2400for 30 students then for how many days will the food last?

Answer 1

Step-by-step explanation:

Rs. 3200 for 20 students for 30 days so per student per day expenditure is 3200/(20×30) = 5.333 Rs

So one day's expense for 30 students=

5.333×30= 160 Rs.

So number of days to use 2400 Rs. = 2400/160-15 days
