Question

If a farmer has to feed 30 animals for 6 days how long would the food last if he had 15 more animals to feed

Answer 1

A farmer has enough food to feed 20 animals in his cattle for 6 days. How long would the food last if there were 10 more animals in his cattle?

Let the number of days be x

Total number of animals = 20 + 10 = 30

Here the number of animals and the number of days are in inverse proportion.

therefore 20/30 = x/6

x = 6×20/30 = 12/3 = 4

Hence the food will last 4 days.
