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

• initially coffee worth = rs126/kg
  mixed with two variety x and y with ratio = 1:1
  (x/2+y/2)=126
  x+y= 126*2
  two variety mixed with third variety z in ratio = 1:1:2
  x/4+y/4+z*2/4=153
  (x+y)/4+z/2=153
  63+z/2=153
  z/2=153-63=90
  price of third variety per kg = 90*2 = rs180/kg
