A camp is planned for a group of 200 children. Food is bought to last for 10 days. If the number of children were to increase to 240, how many days would the same amount of food last? (Assumming that each child consumes the same quantity of food daily.)

When the quantity on one side increases by a certain amount, the quantity on the opposite side must decrease by a proportionate amount.
Eg. If the amount of children halved, the amount of days must be doubled.
200 children - 10 days
20 children - 100 days
240 children - 8 and 1/3 days.
Thanks.
