ex.1 A man buys an article for rs.27.50 and sells it for rs.28.50. find his gain %. sol. cp=rs27.50, sp=rs 28.50 gain=rs(28.50 –27.50)=rs1.10 so gain%={(1.10/27.50)*100}=4% Ex.2. If the a radio is sold for rs 490 and sold for rs 465.50.find loss%. sol. cp=rs490,sp= 465.50. loss=rs(490-465.50)=rs 24.50. loss%=[(24.50/490)*100]%=5% Ex.3.find S.P when (i)CP=56.25,gain=20%. sol. (i)SP =20% of rs 56.25 ,=rs{(120/100)*56.25}=rs67.50. (ii)CP=rs 80.40,loss=5% sol: sp=85% of rs 80.40 =rs {(85/100)*80.40}=rs 68.34. ex.4 find cp when: (i) sp =rs 40.60 : gain=16% (ii) sp=rs51.70:loss=12% (i) cp=rs{(100/116)*40.60}=rs 35. (ii) cp=rs{(100/88)*51.87}=rs58.75. ex.5 A person incures loss for by selling a watch for rs1140.at what price should the watch be sold to earn a 5% profit ? sol. let the new sp be rsx.then (100-loss%) : (1 st sp)=(100+gain%) (2 nd sp ) {(100-5)/1400}={(100+5)/x}=> x={(105*1140)/95} =1260. ex.6 A book was sold for rs 27.50 with a profit of 10%. if it were sold for rs25.75, then what would be % of profit or loss? sol. SP=rs 27.50: profit =10%.
