There were 12 female pups
First, what I did was write 1, 2, and 3 on a piece of paper.
Then, I wrote numbers 1 through 6 around the number 1, because the first litter had 6 pups.
Then, I wrote numbers 1 through 5 around the numbers 2 and 3, because the second and third litters each had 5 pups.
Then I counted all the pups, from all 3 litters, and circled every fourth pup; meaning that pup was a boy
Then I counted all the uncircled numbers, which were all the female pups, which came out to be 12.

Since there were 3 litters, with 1 litter being 6 pups, and 2 litters of 5 pups each, then there were a total of 16 pups

Since 1 out of every 4, or of the pups were males, then 3 out of every 4, or of the pups were females, and since = 12, it's clear that there were female pups.
