• Let P be filled by 60 lts of 1st liquid and 40 lts. of 2nd liquid.
  
  amount of kerosene = (25*60/100) + (30*40/100) = 27 lts.
  
  % of kerosene = 27 %

• let 1 part is = 100 liters
  1 part of 1st liquid contains 25 liters of kerosene
  1 part of second liquid contains 30 liters of kerosene
  so 6 parts and 4 parts of 1st and 2nd contains 25*6+30*4=270
  so 270/1000=27%
