a man sells three article's x,y,z for rs 1386 each.he sells article X at 12.5% loss , article y t 10% profit if there is no profit and no loss in whole transaction.find cp of article Z?

Hi Nunavath Ramesh, It is given, SP_x = 1386 SP_y = 1386 SP_z = 1386 It is also given that article X is sold at 12.5% loss 7/8(CP_x) = 1386 CP_x = 1584 It is given, article y is sold at 10% profit 110/100(CP_y) = 1386 CP_y = 1260 There is no profit or no loss in whole transaction. This implies cost price of all articles is same as selling price. 1386*3 = 1584 + 1260 + CP_z CP_z = 1314 Hope this helps!
