Question

A farmer has enough to feed 32 animals in his farm for five days.How long the food would last if 8 more animals join his farm​

Answer 1

Let the number of days be x.

Given that he has enough food to feed 20 animals in his cattle for 6 days.Later on, 10 more animals were added.

Therefore the number of days required to feed 30 animals:

20 * 6 = (20 + 10) * x

120 = 30 * x

x = 120/30

  = 4.

Therefore the number of days = 4.

Hope this helps!
