a merchant buys 20kg of wheat at 30rs/kg and 40k at 25rs/kg.he mixes and sells 1/3 rd of mixture at 26rs/kg.price at whch merchant should sell remaining mixture so that a profit of 25% on whole outlay is?

• ans) 37rs/kg
  cp of total mixture=(20*30)+(25*40)=1600rs
  as he needs 25% profit, so he needs to earn 1600+(1600*(25/100))=2000rs.
  he has alredy got rs by selling 1/3 part=1/3 of 60 kg..=20 kg
  =20*26=520rs..
  now he needs 2000-520=1480rs.
  so he must sell remaining 40 kg at=1480/40=37rs/kg

• Merchant buys 20kgs at 30rs/kg
  so total c.p.= 20*30=600
  
  Again he buys 40 kgs at 25rs/kg
  so total c.p.=40*25=1000
  
  Total c.p.= 1000+600=1600
  To earn profit of 20% on whole mixture the s.p. should be = 1600*120/100 = 1920
  
  He sells 1/3rd (i.e. 20 kgs) at 26 rs/kg
  so s.p.= 20*26=520
  
  Now he have to sell remaining 40 kgs on (1920-520)=1400 rs
  So price er kg = 1400/40 = 35 rs. /kg (Ans.)

• Total cp = 20 * 30 + 40*25= 1600
  Sp = 125/100 * 1600= 2000
  Sp for 20kg mix = 26*20 =520
  Rem sp = 2000-520 = 1480
  As this sp is for 40 kg = 1480 / 40 = Rs37

• 20*30=600
  40*25=1000
  total=1600
  profit of 25% on total
  1600*125/100=2000
  total mixture is 60 1/3rd is 20
  20*26=520
  remaining=2000-520=1480
  remaining is 40 kg 1480/40=37 perkg
