How do branching ratios affect neutrino fluxes at Earth?

Hello!
I've got this question (attached as jpg) about the neutrino fluxes at earth. I don't know how to use the branching ratios in order to solve it. (Do I really need these ratios?)

Thanks.
Ted.

Simple answer is yes you do. Question involves thinking about what the ratios mean and say about the total number of neutrinos produced.

Plus the wording of the question indicates you are to work out the flux from each branch. Doesn't get more straightforward than that.
