No. of dogs in dogs only households = 24
No. of cats in cats only households = 30
No. of animals in cats & dogs households = 26.
No. of cats = x
(30+x)/(24+26-x) = 5/3
Simplify to get
x=20
So, total of 50 cats and 30 dogs.

No of dogs only 24
No of cats only 30
No of dogs and cats 26
So total number of dogs and cats is 24+30+26 = 80
This is in the ratio C:D = 5:3
So dogs must be 3/8x80 = 30
So C
