Question

In a store the number of dogs is 12 times greater than 3 times of cats. If there are 21 dogs in the store, how many cats are in the store?

Answer 1

If you really meant that the number of dogs is 12 greater than 3 times the number of cats then:

3 cats

Explanation:

21= number of dogs

c = number of cats

21 = 12 + (3c)

3c = 9

c = 3
