• just imagine buying 1/2 kg of 1st variety and 1/2 kg of 2nd variety of the same element we buy it as
  5 rupees of 1st variety and 7.5 rupees of second variety
  adding cost and quantity we get 5+7.5=12.5 rupees
  1/2+1/2=1 kg
  None of the options are correct. Think practically.. Ans is 12.5 rupees
