coffee worth Rs.126 per kg are mixed with a third variety in the ratio 1:1:2 .if the mixture is worth Rs.153 per kg then the prize of the third variety per kg will be?

• let the price of third variety be x,
  total cost of the mixture = 1*126+1*126+2*x
  which is equal to 4kg*153,
  solving it we get,
  x=180.
