Question

A farmer has enough food to feed 100 animals for 20 days. How long would the food last, if there were 25 more animals?

Answer 1

Answer:

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\frac{20}{30}=\frac{x}{6}

x=\frac{6\times20}{30}=\frac{12}{3}=4

Hence the food will last 4 days.

Answer 2

Answer:

100 animals = 20 days

25 animals = ? days

= 25 * 20 / 100

= 25 days ans.

Hence food will last for 25 days for the animals.
