Tea worth Rs 126 kg and Rs 135 kg are mixed with third variety in the ratio of 1:1:2.if mixture worth Rs. 153/kg. the price of third variety per/kg?

• 1st & 2nd varieties are mixed in equal proportions, so their average price = Rs. (126+135)/2=Rs. 130.5
  so, the mixture is formed by mixing two varieties one at Rs. 130.5/kg & other at Rs. x/kg (Let) in the ratio 2:2, i.e 1:1
  Acc. to alligation rule
  (cost of 1kg tea of 2nd kind -mean price)/(mean price-cost of 1kg tea of 1st kind)=1:1
  x-153/(153-130.5)=1 ( mean price=153/kg)
  x-153/22.5=1
  x-153=22.5 x=175.5 (ans)

• let the cost of third variety be 'X' Rs.
  so considering for total as 4kg (1:1:2)
  (126+135+(2*X))/4=153
  by solving it, X value is 175.5
