. A merchant buys 20 kg wheat at Rs.30/kg and 40 kg wheat at Rs.25/kg and mixed them. He sold one-third of mixture at Rs.26, what should be the cost/kg of the remaining mixture, so as to make a profit of 25% on the whole?

• Total investment CP= 20*30 + 40*25= 1600
  Total Mixture= 20+40=60
  Sold 1/3 of 60= 20kg at Rs26/kg
  Remaining mixture= 60-20=40
  Earned 20*26= Rs520
  To get a profit of 25% on whole total SP= 1.25*1600= 2000
  remaining amount= 2000-520=1480
  Hence, cost/kg of remaining mixture 1480/40=37
  i think it shld be 37rs/kg

• 20kg * 30= 600
  40kg *25= 1000
  total 60kg is their
  profit=25%
  total sp= 1600*1.25=2000
  1/3 of 60kg = 20*26=520
  remaing unsold = 2000-520= 1480
  ==> 1480/40 will give ans =37 rs/kg
