C:N Ratio Question and Blood & Bone

Hi

I can get access to Horse manure (fresh), Coir Dust (dry & fine) and Bagasse (shredded sugar cane mulch) relatively cheaply.

I have found their carbon content and how much I want to use of each as shown below;

Horse manure 30:1 & 30Kg
Coir 100:1 & 6Kg
Bagasse 170:1 & 22Kg
Blood & Bone 3.25:1 & ? Kg

I understand how the C:N ratio concept works roughly but need further help.

How much Blood and Bone meal do I need to get to the perfect 30 to one ratio (in Kgs)?

I would be happy if someone could show me the math or any further advice. Thanks.

Cheers
