Lily accounts for 1/3 of the other three species, and Lily: (Rose+Carnation+Chrysanthemum) = 1:3 Lily accounts for1/(1+3) =1/4 of the total.
Carnations account for 1/4 of the other three species. Similarly, carnations account for1(1+4) =1/5 of the total.
Total number =104 ÷ (1-kloc-0//3-1/4-1/5) = 480 branches.
