Сначала нужно узнать зверобой,затем тысячелистник,мяту.
1) 20*(1/6)=3+1/3 кг - зверобой
2) 20*(1/5)=4 кг - тысячелистник
3) 20*(1/3)=6+2/3 кг - мята
Потом всё сложить 4) (3+1/3)+4+(6+2/3)= 14 
Далее вычесть из суммы всех трав того, что возможно найти: 
5) 20-14=6 кг 
Ответ: календулы было 6 килограммов (0,3 от всех трав).
