Solution

The correct option is D 12
Number of puppies one can can feed = 8
Number of puppies 8 cans can feed = $8 \times 8 = 64$ puppies

Number of puppies fed with 8 cans = 40 puppies
Remaining food can feed = 64 – 40 = 24 puppies

We know that 1 can feeds 8 puppies. Then, 3 cans of foods are required to feed puppies.

Thus, 3 cans of food are remaining.

Number of dogs 1 can can feed = 4
Number of dogs 3 cans can feed = $4 \times 3 = 12$ dogs

Thus, the remaining 3 cans can feed 12 dogs.

Hence, 8 cans can feed 40 puppies and 12 dogs.
