if good be purchased for 450.and one third sold at a loss of 10%.at what gain percent should the remainder be sold so as to gain 20% on the whole transactione?

• loss=10 % of 1/3(450)=15 rs;
  20 % of 450 =90;
  so total gain + recovery=90+15=105;
  therefore (105/300)*100=35 %;
  anws is 35%;

• 35%
  
  If remaining 2/3 part is sold for 'x' then,
  (1/3)*450*(90/100) + (2/3)*450*x= 450*(120/100)
  x=27/20
  %x=100*27/20=135
  So gain %= 35

• total c.p of goods is Rs.450
  on whole transaction we have to get a profit of 20%
  i.e.20/100*450=90
  so the total amount we have to get is 450+90=540
  now, 1/3rd of goods which costs Rs.150 i.e. 1/3rd costprice
  here we are selling goods for a loss of 10%
  i.e. 10*150/100=15 is loss
  we are selling this 1/3rd for Rs.135
  total amount we had to get is 540
  remaining is 540-135= 405 this should be get on remaining 2/3rd of goods which costs Rs.300
  profit percentage = (405-300)/300*100=
  35%
