A person bought 8 Kg. of rice for certain rupees.He sold 3 Kg at 10% profit,3 Kgs with neither profit nor loss and 2 Kgs at 5% loss. What is profit or loss in this transaction ?

• suppose he bought @ Rs x per kg.
  
  He sold 8 kg for (3.3 x+ 3x + 1.9 x)=8.2x
  % profit = 100*0.2x/8x = 20/8= 5/2= 2.5%

• let,that person bought Rs.100 per kg rice.
  then a/c to the problem,
  He will sold 8kg of rice=(300+10)+3*100+(200-5)=Rs.805
  hence,profit=Rs.(805-800)=Rs.5 ans.

• let cost price(cp) of 1 kg rice= RS 100, therefore cp og 8 kg rice=RS 800. selling price(sp) of 3 kg rice with 10% profit. sp=[(100+profit)/100]*cp. for 3kg sp=3*[(100+10)/100]*800=330. 3kg NPNL sp=300 and 2 kg 5% loss, sp=2*[(100-5)/100]*800=190. total sp=330+300+190=820,, gain =sp-cp=820-800=RS20 profit. therefore % gain=(100 *20)/800=2.5%

• suppose he bought rice for 10rs/kg
  then total=(11*3)+(10*3)+(9.5*2)=82
  x=2*100/80=10/8=2.5%
