Question

For $9$ cows, $13kg500g$ food supplement are required every day. In the same proportion, how much will be needed for $12$ cows?

For 9 cows food required daily=13kg 500g.

9cows=13,500kg.

For 1 cows =$\frac{13.500}{9}=1500g.$

$\therefore$ for 12cows food required $=1500\times 12$

=18000g

for 12 cows food required =18kg.
