KALPANA G  (13 years ago) Best Solution

cost price of mixture=(100*selling price of mixture)/(100+profit)=(100*6)/(100+33.5) =600/133.5=Rs 4.50(approximately),
Then ratio of A and B = (4.50-3):(5-4.50)=3:1,
Therefore Brand A in 40 pound mixture=40*3/4=30 (ANS),
and Brand B = 40*1/4=10.

29.8876 pound of A.
SP of mixture = 240 bits
CP = 240*1000/1335 bits .= 179.775 bits

selling prize=40*6=240 bits,,profit is given as 33.5%.i.e,33.5*240/100=80.4bits.
profit=selling price-cost price,so cost=240-80.4=159.6(160)....so cost of the product is divided accordingly for 40 pounds,,20*5=100 & 20*3=60(100+60=160)so 20 pounds of brand A is used.....

if X is amount of A in 40 pound mix then 40-x will be B.....earn toatal amount will be 40 pound*6 bit/pound=240...total cost of mix =5X+3*(40-X)=120+2X,,NOW PROFIT=[120+2X] +[(120+2X)*0.67]=240;
X (A IN THE MIXTURE)====11.85

nihal dang  (9 years ago)

cost price={(40*6)*100}/(100+33.5)=179.7=180(approaximately)
x+y=40,5x+3y=180
solving dis we get x=30(ans),y=10
