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%
