Sol: C.P=Rs 490 S.P=Rs 465.50 Loss=C.P-S.P=490-465.50=Rs 24.50 Loss%=(loss*100)/C.P% =(24.50*100)/490%=5% 3.Find S.P when C.P=Rs 56.25 and Gain=20% Sol: S.P=[(100+gain%)/100]*C.P S.P=[(100+20)/100]56.25=Rs 67.50 4.Find S.P when C.P=Rs 80.40,loss=5% Sol: S.P=[(100-loss%)/100]*C.P S.P=[(100-5)/100]*80.40=Rs 68.34 5.Find C.P when S.P=Rs 40.60,gain=16%? Sol: C.P=(100*S.P)/(100+gain%) C.P=(100*40.60)/(100+16)=Rs 35 6.Find C.P when S.P=Rs 51.70 ,loss=12%? Sol: C.P=(100*S.P)/(100-loss%) C.P=(100*51.70)/(100-12)=Rs 58.75 7.A person incurs 5% loss by selling a watch for Rs 1140 . At what price should the watch be sold to earn 5% profit? Sol: Let the new S.P be Rs x then, (100-loss%):(1st S.P)=(100+gain%):(2nd S.P) (100-5)/1140=(100+5)/x x=(105*1140)/95=Rs 1260 8.If the cost price is 96% of the selling price,then what is the profit percent? Sol: let S.P=Rs 100 then C.P=Rs 96 profit=S.P-C.P=100-96=Rs 4 profit%=(profit*C.P)/100% =(4*96)/100=4.17% 9.A discount dealer professes to sell his goods at cost price but uses a weight of 960 gms for a Kg weight .Find his gain %?

Sol: {[(100-40)/100]*[(100-20)/100]}%=(60*80)/(100*100)% =48% single discount is equal to (100-48)%=52% BACK
