A hostel had rations for 60 days for 500 students. After 12 days, 300 more students join the hostel. How much long the remaining food will last? Please help me solve this tricky question. Thanks.

after 12 days the food would last for 60-12=48 days for 500 students but 300 more students join so total students become 500+300=800 students.

let x be the days the food lasts-

it is a case of inverse proportion




the food will last for 30 days.
