Type A, 18 kg of rice worth Rs. 45/kg is mixed with Type B, rice worth Rs. 35/kg. What should be the quantity of Type B rice, if the mixture is sold at Rs. 54/kg with 20% profit added in it?

• The ques seems to be wrong....
  If we apply alligation we do not get the ans and normal procedure gives -9 which can not be correct

• the total cp of type a rice is 18*45=800
  let the no.of kgs of rice b is x
  total cp of type b rice is x*35=35x
  total cp=800+35x
  18+x kg of rice cost is 800+35x
  1kg cost is (800+35x)/(18+x)
  sp=(100+g%)/100 *cp
  54=120/100 ((800+35x)/(18+x))
  x=9kg

  let no. of kgs of rice b is x
  c.p. of rice a =12*40=480
  c.p. of rice b=24x
  avg. price of rice mixture=480+24x/12+x
  calculate c.p. of the mixture with
  c.p. =s.p.*100/(100+gain%)
  so, price of the mixture is 45*100/100+25=36
  therefore,480+24x/12+x=36 =>x=4
