Question

a hostel had rations for 60 days for 500 students. after 12 days, 300 more students join the hostel. how long will the remaining rations last?

Answer 1

60-12=48
500-300=200

so 48 days for 200 students will the remaining rations last

Hope it helps you

Answer 2

the total ration is the product of the days and students.
 r = d × s
total ration = 60*500 = 30000
in 12 days, the ration completed = 12*500 = 6000
remaining ration = 30000-6000 = 24000
additional students = 300
now, total students = 500+300 = 800
also,  r = d × s
d = 24000/800 = 30 days
the remaining ration will last 30 days

:) Hope this Helps!!!
