All the vipers at the Vennsylvania Zoo are colored either violet or vermillion. Half the vipers are venomous, and 3/4 of all venomous vipers are violet. There are 10 more non-venomous violet vipers than non-venomous vermillion vipers. If there are 23 non-venomous violet vipers, how many venomous vermillion vipers are there at the Vennsylvania Zoo?

Let's show our steps by getting an answer instead of saying an answer without showing steps and also not make mistakes.

 

 

Number of non-venomous violet vipers

                                                 = 23

     

 Number of non-venomous vermillion

                 vipers = 23 - 10 = 13

 Total number of non-venomous

      vipers = 23 + 13 = 36

 

 

Number of Venomous vipers

           = 36 [ Venoumous vipers

                      = Non-Venomous vipers ]
Number of venomous violet vipers

                      = 3/4 * 36 = 27

 

So, Number of venomous vermillion

                  Vipers = 1/4 * 36 = 9

      There are \(\boxed{9}\)venomous vermilion vipers in Vennsylania zoo.
