Question

A holiday spends ₹3200 on food for 20 students for 30 days if they spend ₹2400 on food for 30 students for how many days will the food last

Answer 1

Answer:

3200 -2400

30+30

subtract both answer from 20

Answer 2

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
