Answer :
Solution: The number of dogs left after 25% are decreased, is 9 and number of dogs decreased by 3.
Explanation:
Let the number of dogs after decresing 25% be x.
It is given that the number of dogs are 12 after that he number of dogs decreased by 25%.
First we have to find 25% f 12.
[tex]12\times \frac{25}{100} =12\times \frac{1}{4}[/tex]
[tex]25\% \text{ of }12=3[/tex]
Since number of dogs decreased by 25%, therefore subtract 3 from 12.
[tex]12-3=9[/tex]
Therefore, the number of dogs left after 25% are decreased, is 9 and number of dogs decreased by 3.
