Question

A farmer has enough food to feed 30 animals in his cattle for 8 days. How
long would the food last if there were 10 more animals in his cattle ?

Answer 1

Step-by-step explanation:

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.
