Would be 101 if 4-flake purple flower is worth same as 5-flake purple flower, but I suppose number of flakes is the catch, as 101 would be trivial and there would be no point in introducing 4-flake kind of flower.
If "value" of "crippled" purple flower is undefined then result is undefined.
However, if we would assume that "value" of purple flower is proportional to number of flakes (can make sense because "value" of 5-flake purple flower is 5) then 4-flake purple flower would be 4, then result is 81.
