Last Answer : a = 7/8 , x = 60 % , b =1/12 , y = 32 % , z = 24 % and R = Rs150 Required CP of books = (150*100)/(7/8*60+1/12*32+1/24*24) =15000/(52.5+2.66+1) = 15000/56.16 = Rs267
Description : A salesperson has goods of worth Rs.12000. He sold half of the goods at a gain of 24%. At what profit per cent should he sell the remaining half of the stock so that he gets36% profit on the whole?
Last Answer : CP of goods = 12000 For 36% gain, total SP =12000 + (36/100*12000) = 16320 SP of goods worth 6000 at 24% profit = 6000 + (24/100*6000) = 7440 Therefore, SP of remaining goods = (16320-7440) = 8880 Let ... % for remaining goods be x. Then, =>6000*(100+x)/100=8880 =>100+x=8880/60 x=148-100=48
