There are 6 times as many dogs as cats. Then there are 18 dogs

Solution:

Let the number of cats be "a"

The number of dogs is 6 times more than the number of cats

Then number of dogs is 6a

Total number of dogs and cats = 21

Hence we can say,

a + 6a = 21

7a = 21

a = 3

Hence there 3 cats and number of dogs is 6a = 6 x 3 = 18

Hence there are 18 dogs
